2006 Honda Accord 4 cylinder EX-L.

Problem with a P0139 code.

I posted in the last thread that in early January the check engine light came on and Autozone gave me the above code (plus another dealing with AB-S, code 61-1). I unplugged the battery, hooked it back up, and drove probably 1500 miles with no problems.

The CEL light came on again 2 weeks ago, so I figured it was the O2 sensor (the one underneath the heat shield by the cat). I bought the part off Amazon, replaced it last week, and it was driving fine. I pulled the battery cable off again in order to reset the CEL.

I've been driving it fine with no problems (average 50 miles/day, so a total of maybe 200-250 miles). Then this past Friday, the CEL came on again, so between me pulling the battery cable after I installed the new O2 sensor, I'm guessing I had around 200 miles on it.

Brought it back to Autozone today-P0139 code again.

What else could be the problem? It's been brutally cold here in New England, so I'm wondering if moisture on the sensor is causing it to gently caress up maybe? Anything else I'm missing? Oddly, the other code went away this time and only the P0139 code popped up.

I figure you guys have experience buying cars privately, so I think this is the best place to put this.

Some background: My wife and I are getting a divorce. Both cars are currently in my name but I'm giving her one of them (which is paid off and I have the title for).

Here's the hard part:

Current plates are Arizona (as is the title), and we live in Massachusetts (which is ok because I'm military and AZ is my home of record). She's moving down to North Carolina.

For title transfer, what is going to have to occur?

I see on the title I can fill out the transfer of ownership and have that notarized. Can I just do that, then she can drive the car down to North Carolina and register the car in that state, getting herself new plates? It says the buyer (her) has 15 days to transfer ownership, so I'm trying to see the best way to do this.

I'm trying to think of everything here-she'll be coming off my insurance and establishing her own (with the same company if that makes things easier) policy.

What's the best way to do this? Would it be better for her to drive down there on my insurance (which she could still be on for this purpose) and then once she's down there I send her the title and let her register/get insurance in her own name?

Or should we transfer the title up in MA, get new insurance for her, then she drives down to NC (literally the next day) and gets plates/registers the car down there with title in hand?

Or something else I'm not thinking of?

edit: She'll be towing the car behind a U-haul, so she won't physically be driving the car until she gets down south, if that alleviates anything.

Stupid insurance question:

My wife was backing up the car and hit the mailbox. The right rear quarter panel is dented and paint is gone. It's a 2011 Ford Explorer.

She took it to a body shop and they said it would be over 500 to repair it with paint and dent removal, etc...I think they were going to replace the body panel.

Anyways, my insurance deductible is $500 for collision and adds 350 to my annual premium.

There's another deductible that is for theft and 'other than collision' which is only $300 and adds 90 to my premium.

Would this fall under collision even though it wasn't an accident with another car?

I've always understood it to be where collision is what pays you if you do damage to your own car (i.e. this scenario) and comprehensive covers you for situations where it wasn't your fault, but there's not necessarily another party to blame.

How do you figure the "adds $350 to my annual premium"? Are you reading your bill, because if so, that's not what making a claim would add to your premium - that's what you're paying for that coverage.

You're right on that-i was reading it wrong. I pay 350 a year for that coverage.

Is it possible for a car battery to be completely drained to the point you cannot jump start it?

I left my Scion TC off for the winter, and it appears the battery is completely dead. When I turn the ignition there is no sound.

I tried boosting it, but for the love of me, it won't start. I have tried two different "donor" cars to boost. Besides connecting the positives to the positives, and negatives to the car frame of the dead car, is there something else I should be doing?

Would it make a difference if I ran the donor car for a bit prior to trying to boost the dead one? Does the car matter? Would a pickup truck have a better chance at boosting it?

one of the negatives is connected to the live battery, correct?

Not acting like I know much, but one time I tried jumping a dodge truck with my civic and it wouldn't work. Then another truck came along and it jumped it fine. Maybe my battery wasn't strong enough? I don't know.

I've had trouble jumping batteries before, though...and sometimes I'll let the live car run (while it's connected to the dead battery with cables) for a few minutes and then try, and that seems to help.

I need some new tires but I'm not sure to go with winter or all seasons.

I have a 2015 Mazda 3 hatchback itouring 6 speed manual model with the stock Bridgestone ecopia tires and last year they sucked in the small amount of snow we got (Boston, MA).

The two years prior to that, I had a Honda Accord with some continental all seasons and it did fine in the snow, even when we had a lot more of it.

Now I know it's two different cars and the Honda was probably heavier, but the Bridgestone has lovely snow ratings.

Now I'm at 26k miles and am thinking of getting a set of Steel rims and some dedicated winter tires, or just trading in the lovely all season OEM bridgestones for a better all season tire.

Any advice? I'd rather not spend $6-700 plus now on winter tires and then in the summer have to spend another 5-800 on new all season tires, but if other all seasons are going to ride just as bad as the bridgestones in the snow on this car, then maybe I need to.

2008 Saturn vue with the 4 cylinder 2.4.

It has 115k miles on it and always got the normal oil changes, I just changed the spark plugs but it probably needs the transmission fluid changed.

Anyways, it has a few random squeaks now and I'm not sure what it could be. Most recently, after a 3 hour drive, when we turned into the gas station it just sounded like it was squeaking pretty bad when we turned the wheel. I don't think anything related to shocks but more the steering system? It was coming from the front of the car but that's all I know.

Also, for a long time, when the wheel gets turned slightly to the left or right, there's an oscillating sound I'm thinking might have to do with the brakes. It's kind of like if you had a rim on a bike that's slightly out of true and you put it on a truing stand and once per revolution it hits the metal, that's the sound it makes.

I'm probably going to have to take it to a mechanic to really find out, but any shots in the dark as to what could be wrong? Also, for the first problem-could the chassis or something else potentially just need lubed up? I remember when I brought other cars in for service they would say lube the chassis as part of the tune-up, and I've just been bringing it to jiffy lube for oil changes so I doubt they have been doing that.

Just wondering if I can also request some basic tune up that won't charge an arm and a leg to fix everything.

Also, I was quoted $225 for the transmission fluid to be changed-Rip off or average cost for this?

Check that your power steering fluid level is okay. If it's a bit low - things can act weird.

The sound that has to do with the brakes - it might just be the brake dust shields touching the edges of the rotors. Have a brake inspection done - most shops do brake inspections for free. Ask for the pad measurements - how many 32nds are left. They start new around 10 or 11/32. Replace when they get down to 2 or 3/32"

There's really nothing to lube on the chassis on a Saturn Vue - like most modern cars. The ball joints on 95% of cars don't have grease fittings anymore. Tie rods haven't had them for years in most cases either. There's no u-joints or idler arms or pittman arms or any of that on a VUE either.

I'll let someone else weigh in on the transmission flush - but I'm wary of the flush process. I've heard things. All I'd do if it were my own car is a drain-and-fill.

Tune up? On a vue - the tune up is simply the spark plugs, air filter and fuel filter (if it's serviceable - some cars have it only in the tank) And if your're feeling really fancy - the PCV valve.

Thanks for the reply!

The brake dust shields...you might be right on that and it seems like it should be easy enough to check out.

I didn't know about new cars not needing to be lubed up. I just remembered seeing it as part of "101 point inspections" at dealerships and stuff.

Still not sure on a transmission flush/drain and fill. I've heard it's best to just drain and fill it consecutive with 2 or 3 oil changes in a row. That's what I did with my Accord when it hit 100k miles, and after 3 transmission drain/fills you're basically sure you've got about 90% new oil in there and that should be more than good enough.

Two questions:

Possible exhaust leak question:

2008 Saturn Vue with the 4 cylinder engine and 120k miles on it.
Driven entirely in New England for the last 5 years by my wife-before that, I'm not sure where it was driven.

I brought the car in for the Massachusetts state inspection today and the mechanic said it passed, but there was an exhaust leak I need to get checked out. All he said was that it was coming from the front right of the car-he started it up for me and, without opening the hood, just pointed towards the passenger headlight area and I did hear some kind of leak...not necessarily hissing like high pressure, just more like what you hear out of a normal exhaust/muffler if that makes any sense.

Going off that horribly vague description, any ideas? I know my wife bought it off a used car lot her dad worked at and only the bare minimum maintenance (really just oil changes) has been done since she bought it 5 years ago (she bought it with about 75k miles on it...she rarely drives it anymore). I know she never really used to wash it during the winter, because it has some spots on the car (door panels) where the paint is bubbling up and I'm guessing that's salt damage, so who knows how bad the undercarriage is. Over the last two years I've ensured we wash the undercarriage a few times during the winter to get rid of the salt.

Appreciate any advice/insight before I take it to a mechanic. If it passed inspection this time, it leads me to believe that the leak might not be too bad yet, or else I would have some kind of engine codes popping up saying that the right mixture isn't going past the O2 sensor or something, but I'm not anywhere near an expert on this stuff.

Sounds like it could possibly be your exhaust manifold has a leak, or rusted out perhaps. Sometimes header bolts can warp and expand causing your exhaust to make noise from the front of your car near where it was pointed out to you.
You can probably find a shop near you in Mass. that just works on mufflers/exhaust. These guys will be able to spot it right away and get you sorted out; as opposed to taking it to a general mechanic who doesn't specialize in exhaust. That mechanic could still get it sorted, but with muffler/exhaust issues, I take it right to the pros who specialize in that specific work, if I can't fix the issue myself.

SA username : "STR" is the resident Saturn expert, you could probably PM him for Saturn specific exhaust issues to get a better feel for what you might be looking at before you take it in.

This is great info-thank you. Googling the issue says either exhaust manifold or the gasket. I just took a look under the hood, but there's so much plastic covering everything up, I removed what I could and then it looks like even the manifold appears to have some kind of plastic covering on it, so that's where I stopped. A few of the bolts had some rust on them, so I didn't bother trying to tighten them down (some people online said 1/4-1/2 turn tighten on each bolt could solve the issue, but some people said they snapped the heads off when trying it with rusted bolts).

I'll reach out to STR and see what he has to say-I didn't even think about an exhaust/muffler shop instead of a general mechanic-that's a great idea.

I don't mind doing work on it myself too much if it doesn't require taking the whole thing apart, but I'm clueless on how to look for a leak. Some research said to use seafoam or something similar and that will expose a leak quickly, but I'm hesitant to use that on a car with 120k with minimal maintenance done on it.

Also I don't detect any exhaust smell in the cabin and moving my hand around the engine bay when the engine was on, I couldn't feel any puffs or air from the exhaust, though I couldn't reach much of the manifold.

STR posted:

So yeah... following up on nwin's PM - the exhaust manifold is on the firewall side. Dennis has good advice about going to an exhaust shop, but you can at least look for the leak yourself. Remove the plastic engine cover, get on the drivers side with the engine running (away from the belts - don't want your hair, shirt, fingers, etc getting caught in anything), and just listen for pfft pfft noises. It'll help if you turn off the ac before starting the engine - that way the cooling fan shouldn't be running.

You mentioned in your PM that your mechanic mentioned the noise was up toward the front, that could just be the air filter housing cover not being attached properly (it could hiss a little bit). I know on my Ion, the cover is a pain in the rear end to line up right.


:catstare:

I think FAT32 Shamer knows a bit more. At least he acted like it for awhile. :v: But the 2nd gen Vue is just a rebadged Chevy Equinox with slightly different lights (the 1st gen borrowed a drivetrain from Honda for the V6 models though, and actually had plastic body panels and Saturn-esque styling, though it was still essentially an Equinox).

I'm not sure if it's actually an exhaust leak at this point. I checked the air filter housing cover, and aside from one of the screws being nearly completely rusted out, the cover is on correctly. The sound that I hear when I'm listening near the passenger headlight is the serpentine belt going around...definitely not a hissing or puffing sound though, or even a squeaking sound like I've heard on some belts before. I moved my hand around the back of the engine bay and didn't hear anything like a pfft noise. I'll check again tomorrow when I have some more time.

The serpentine belt doesn't appear to be cracked or rotted. If anything, the exterior of it looks shiny, kind of like when brakes get glazed over?

2008 Saturn vue with 130k miles has a problem with its rear brake light.

I noticed a week ago that the drivers side brake light was out. I bought a pair of replacement lights, one for each side, and replaced them both, figuring that if the drivers side was out, it wouldn’t be long until the passenger side went.

Today someone pulled up to me and side the drivers side was still out. Note: I didn’t bother checking when I replaced the bulb to see if it worked-whoops.

Now, could this be a fuse problem? The way I’m reading online is that the fuse usually controls both lights, so I’m wondering if it’s a wiring issue or something else.

If it uses a 3175 (dual filament combination tail/brake/signal bulb) its possible you have the base inserted backwards.

Is there an electrical/wiring thread or should I just post here?

I bought an aftermarket remote start for my 2008 Saturn vue that was “plug and play” but the instructions have me splicing wires and I’m not entirely sure what to do. I think it’s because the car has passlock.

Note: it doesn’t have me cutting into the car’s harness...yet, just cutting the harness they provided.

If I were you I'd read the rest of the instructions to see what's up. Hopefully its just like a radio harness where you splice things outside of the car then just plug everything in.

Here’s the instructions:


Just a wiring diagram. On the other side it shows that the pink wire on the car’s harness is the ignition and the white/black wire is the passlock.

Here’s the harness they supplied with their VS3 cut off and those two wires exposed:



And here’s the car’s harness showing the black/white wire and the pink wire, but it still goes into the plastic connector:



So what do I do from here? I can’t stick the harness’s exposed wire into the black plastic connector on the car’s harness, right? That doesn’t seem like it would make a good connection.

The only other thoughts are exposing some of the wire on the car’s harness before that connector and tying the remote start in that way.

Krakkles posted:

It definitely looks like some stuff is missing. But:

If you want to connect that, you'll need to get the appropriate wires (the instructions appear to say that a pink and yellow should be hanging off, not pink and black/white), find the appropriate wires in the car's harness, and do one of a few things:

Ideally, cut them, solder or crimp them together with the new harness. There's some debate as to whether soldering or crimping is better, but I think the general consensus is a good solder is better than a mediocre crimp, and a good crimp is better than a mediocre solder, so whichever you can do better is probably the way to go.

Here's ChrisFix's guide to soldering wires: https://www.youtube.com/watch?v=Zu3TYBs65FM

and EricTheCarGuy's guide to crimping: https://www.youtube.com/watch?v=i5LBf19MqPk

The advice I wish someone had told me earlier: Get the right tools. I thought I couldn't solder for years, because I was trying to do it with RadioShack soldering irons that were crap. I got a Weller and instantly found that I could solder just fine. Same thing with crimping - I was trying to use an autozone special, I could never get it to work, got a BluePoint, suddenly it works every time.

You could also skip those harder options and use vampire taps, but you really shouldn't do this - they're a lot easier to install, but they're much more prone to failure, and they almost always end up causing phantom electrical problems later.

The last thing I'd say: This probably isn't the job you want to learn on. Once you cut the wire, your car isn't going to work until you figure it out and get it back together. Practice on random wires first, at least.

Good catch on the wire colors-the white/black is on the car side and it matches to a yellow on the harness side I think-is have to double check in the morning.

That being said-I don’t think I want to cut into the car’s harness for this. Like you said, if I gently caress this up, then I can’t start the car until it’s fixed, and that’s not worth it to me. I might either have this installed or just return this thing.

AWD systems depend on wheel speed sensor inputs and are extremely sensitive to wheel diameter. Unfortunately they are telling you the truth, though 3 tires is a lot cheaper than a new AWD transfer case.

So I’ve always heard to replace them all. When I had a forester, I caught something in my sidewall and all four tires needed replacing, even though they only had about 15k miles on them. They also refused to shave a new tire down and several other places said the same.

When I bought my Lexus AWD gs350, they tried to sell me a rim and tire warranty. I asked them if they would replace all four tires in the event something similar to the above happened and they looked at me like I was crazy and that there was no reason to replace all four tires.

17 Lexus gs350 with 45k miles. It was just inspected, had its 45k service done about two months ago.

The battery is dead for the second time in three weeks. During the maintenance they said the battery was fine (well the sticker says green next to battery and tires).

I don’t drive much. I haven’t driven it since Monday (now Saturday) and that was for about an hour. Prior to that I’d taken a few 45 minute trips.

anyways, it’s 20 degrees out so I’m thinking the cold plus it possibly being a 6 year old battery (I bought it CPO with 40k miles 8 months ago) plus not driving much means it either needs replaced or charged.

Good ways to check? If I jump it it starts up pretty quick. I have a multimeter if that’s any help.

At 6 years old, unless your battery is an AGM, your battery is almost certainly dead. You can use a multimeter to check the charge level of the battery (should be 12.6 or higher if good), but to get a true test on the battery, you have to load test the battery. Any auto parts store or battery store should be able to do that for free, but from what you describe I'm 99% sure it's your dead battery. The cold weather probably finished it off.

I just checked the date and the battery is from august 2020. I’ll check the charge with a multimeter but will that be any good with a dead battery or do I need to jump it first?

Probably not, the battery will be low if it can't start your Lexus. Jump it, drive it for thirty minutes (not just idle), turn the engine off and test it. If it reads above 12.5, wait an hour and test it again to see if it is draining quickly. If it still seems good, let it sit and test it the next day.
If it is losing charge, it could be the battery is not holding a charge well, or you could have something in your car draining the battery. Next step would be to make sure the battery is charged and take it to where you got it for a proper load test and possible warranty replacement if it's bad. If you bring a battery in below 10 volts, most places will say the battery is too deeply discharged and possibly out of warranty because of that (the Batteries Plus I work at would, at least).
If you get the battery tested and it is good, or you get a new battery and you keep having problems, post here and I can walk you through on how to test for drains.

Thanks. I learned my multimeter sucks. It’s got 10 or 250 V for DC. It took a bit to jump it. I tried right after connecting the cables with the other car running and it took about a minute before my car finally turned over.

Drove it for 40 minutes and it pinned the dial at 10v and at 250 setting it was at 18 which seems high…or I’m not reading correctly.

Waited an hour and I got the same readings. A new multimeter is coming tomorrow.

So 24 hours later and the old multimeter still pins the needle at 10v. At 250v it was higher, around 20v today.

New digital multimeter shows 11.9v today.

in nwin's case, i would suggest further diagnostics. ok, it's under 12V when sitting, that's bad. but it could be due to a parasitic draw in the electrical system, or an alternator that isn't charging it properly.

i would recommend jump starting the car, let it run for a bit, then measure the voltage at the battery with the engine on. it should be in the range of 13.8V - 14.8V. If it's not, or it's fluctuating, I would start to suspect something in the charging circuit.

Once the battery has been charged up for a bit, I'd shut the car off and then disconnect the negative battery terminal. That way, there is no load on the battery. Measure it, it should be well over 12V. Probably closer to 13V. Then let it sit overnight, still unplugged. Ideally it should measure 12.6V. I wouldn't be too concerned about plus or minus 0.2V or so.

If it starts out at an OK voltage but self-discharges (with no load) to below ~12.6V, that indicates that the battery is not holding a charge and should be replaced. If it's fine overnight, then I would suspect that there's something in the car that's draining it. You can find the drain by using a clamp-on ammeter, or pulling fuses with a meter in series with a battery cable.

Going to get the battery checked tomorrow but I ran the ammeter with the clamp on it before and after I uninstalled my remote start.

>1.5A draw from a remote start? yeah that'll do it

Is the 1.12A draw I’m still experiencing “acceptable” or should I continue the hunt for draining items? The only other thing I’ve done to this car is install an aftermarket CarPlay add on. No reports on the web of this specific brand contributing to any drainage issues.

Also, would the 1.5A draw from the remote start be acceptable if I were driving every day?

I think you guys might be on to
Something…

I opened the hood, closed the doors, put the key fob in the house and waited 25 minutes. Here’s where we sit:



Does that translate to 80 milliamps?

Thanks. I went to advance auto and had them check everything including a load test. Alternator and battery both were fine, just the battery was undercharged- I think he said the battery is rated for 540 CCA but only putting out 350CCA currently.

540 is a pretty small battery for any car.

Also I'm guessing they didn't use a proper carbon pile load tester, just hooked up a little electronic thing, right? The carbon pile testers are essentially space heaters that hook up to the battery with some electronics, and the battery has to be fully charged before testing. The small electronic ones are garbage for actual testing.

Yep, just something that looked like a really fat tablet.

Yup, agree with STR. False good is too easy with those. There is some value to them, as if it tests bad and you're having problems, then that is pretty much right. Kind of like a covid rapid test :v:

Well this isn’t helping anything. What’s my other option here? Find a auto store which has the bigger tester?

So stupid question. If I'm going to pull fuses while seeing if the ammeter changes, would this be a good guess:

If it's pulling 700 milliamps currently, should it only be fuses marked 7A and below that I should pull? Apparently I've got four fuse boxes in this thing and after a quick glance the fuses seem to range between 5A up to 40+A.

Do I need to pull them all or could I limit it to a certain range of fuses?
