UPDATE: Problem with GenIII (2005) - 02/08/14 06:02 AM


I had the codes pulled today, and here's what I got:

- eng codes po174 (lean bank 2) po171 (lean bank 1)
- anti lock brakes and brake booster codes 35 & 36 (steering wheel sensor)
- tps code 25 (low battery on tire 2)

And then the garage my invoice says "would need to do more diagnostics". Any thoughts on these codes? I would like to replace the alternator, but with going through this divorce, it might be awhile before I can get that much cash together. Do you guys think there is any risk of doing more damage by running it like it is? TOday I drove it quite a bit, and only the Service Engine Soon light came on, and I noticed it is idling low (under 1k). Seems to run fine otherwise. It does seem that the brakes require more pedal pressure than normal, but maybe that's just a difference between my old '95 and this one. I'm still not at all used to this vehicle <img src="/forums/images/graemlins/frown.gif" alt="" />

Thanks guys.

I bought this thing near the end of November with 87k miles on it. Clean car fax, immaculate condition. 0 problems with it for the first couple months. The other day I got up early and drove it to a hiking area 30 minutes away. My daughter and I hike for a couple hours and drove home. Then boys and I loaded up the tubes/sleds and hit the big hill about 10 minutes away. We were there over 2 hours. Went to leave, and it would not start. Turned over fine, but no fire. I tried holding pedal to the floor, and pumping the pedal with 15 minutes between attempts. Nothing made it even sputter. So AAA takes it to the shop. Shop dicks around with it for over a week (The same week in which I was served divorce papers while at work). Shop finally takes it into shop, and says, it started right up, nothing wrong. I told them to change the plugs and wires, so they did. 287 bucks. I drove the car home no problems. Next morning, I get in to drive to work, and traction control on and off lights are BOTH light solid, and so is the service engine soon. Low air pressure light is lit as well. Now sometimes none of those lights light up. sometimes just the service engine soon light sometimes both the traction control lights. I'm really, REALLY hoping someone will have some input on this. I'm on the verge of being kicked out of my house (oh but I will be PAYING FOR EVERYTHING). My kids are taking this brutally hard. I can't take not having a dependable vehicle. I'm about ready to put it out for sale. Just over 90k on the ticker, but I can't be putting tons of money into it, as I now have a car payment for the first time in 16 years. Please, Mitsu Masters, give me some clues/advise/wisdom or tell me to piss off. I'll be ready for any and all responses.

Sorry on the troubles ... Shocking on how the 'modern women' will divorce at the drop of a hat... <img src="/forums/images/graemlins/confused.gif" alt="" />

On the truck ... I would clean and move around all the plugs under the hood .. It a Mitzu so the plugs under the hood and ECU can come loose ...Try moving the plugs and wires as the truck runs and see if it dies....

By plugs, haztoys means the electrical connectors under the hood. Also look at the connections on the ignition switch. You could have a loose connection there causing the starter to engage, but no power to the ECU.

Dang men. No loose plugs. Everything looks ship shape. I disconnected/reconnected everything I could get my hands on. The service Engine Soon light is always on. Sometimes the traction lights are lit, sometimes theyre not. It has started okay so far, but I just have no faith in this thing. It's realy clean. Anyone want an '05 Montero Limited? I'll make ya' a deal. smile

This may be a dumb question, but have you tested the battery and alternator? I am wondering if you are getting low voltage that is causing your issues. My Gen 2 would start fine with a battery that had a dead cell.

Getting the battery tested, and checking the battery cables and grounds would be a good idea. I had a battery short out internally causing all kinds of crazy intermittent things to happen - blinking lights, sunroof opening, horn honking etc.

My battery went from "hmm, wonder if something is up?" to "holy chit what is wrong?", all in less than a week. Truck would stop running pulling away from a light. Other times the radio would shut off and clear all presets. Lights on dash. Took a look and the thing was four years old...

Re: Problem with GenIII (2005 - 02/17/14 07:58 AM

Thanks guys. Everything looks good, and the battery checked out. I had to drive the thing to PA over the weekend for my daughter's bball game. When I left town, the Service Engine Soon light, and both Traction Control Lights were on. About 45 minutes into the drive, the traction control lights went out, and the front diff light started blinking. The rear wheel indicators were out. Same thing happened on the way home. Just driving around town, the Traction control lights come on about 15 minutes into driving, and if I drive long enough, they go out and the diff light blinks. I'm taking it in Thursday to have the antenna replaced (it got broken at work and is being paid for by employer). I'm going to ask the garage to hook it up to the diagnostic machine and see what it says. My question for you guys, is should I try disconnecting the pos terminal and resetting the codes before taking it in? It didn't start doing this until after I had the yahoos at the other place replace the plugs and wires. I thought maybe resetting would clear things up. Thanks men.

If the battery was checked out, wasn't it then disconnected at the same time? You don't want to clear any codes right before taking it in as it needs time to log them.

Autozone hooked up a box to the system and said all was fine. I thought I would clear it, then drive it a few days. I have to make a trip to Columbus on Wed and its going to the shop on Thursday. If you think I shouldn't, I won't clear it. Thanks man.

I had an intermittently bad alternator do a bunch of things you are describing and worse, chased the problem around for months. sometimes the truck would just blow a 40amp fuse as soon as i keyed on and i couldn't drive the truck for a week or two then it would be fine. One day i took it on a 4 hour road trip with no issues and when i got home a ton of smoke came out of my alternator and all the dash lights went on again and my voltage dropped on the gauge. After that i replaced the alternator and never had a problem again.

Not saying that is your problem but it's something to check out.

I updated my original post with what I found out at the garage today. Doubt it will help much. I'm going to try to replace the alternator as soon as I can. Thanks for the information men.

Autozone hooked up a box to the system and said all was fine.

Their box said the same thing about my battery (which was 5yrs old and bulging on the side) and my alternator (that was causing my headlights to pulsate). Doesn't seem to be a very in-depth test unfortunately.

Personally I just replace both if I'm at all in doubt, which I figure costs about the same as having a knowledgeable shop do a thorough diagnosis.

Our 03 stops like a sports car compared to my 00.

Idle should be ~750rpm.

How long does it take to throw the codes, etc.? If it happens fast, come to me and we can throw the 03's in yours. Can't take it out for, say, a week's test as it is the wife's DD. but we could swap for a couple hours.

Re: UPDATE: Problem with GenIII (2005) - 02/25/14 12:57 AM

Man Bill, that's really gracious of you. The codes have always come on shortly after starting. I think the longest they ever went was around 45 minutes, during a highway trip. Around town, they come on within the first few minutes. Not always in the same order, or the same lights at the same time. I'm really worried this is going to turn into a lemon for me <img src="/forums/images/graemlins/frown.gif" alt="" /> Not what I need right now (but then again, when does anyone need a lemon?). Could my car damage your alternator? I really don't want that to happen.

She just told me last night that her 'wheel-drive' lights are misbehaving. I'll have to try and take a look at her situation and see what gives.

I don't know either way how readily your truck might thrash her alt if we dropped it in for a few hours. Anyone else have thoughts on this?

Any updates on this bud? Hope you're getting it sorted. Why is it that when things go awry, they occur in multiples? Hope things turn the other way for you soon! <img src="/forums/images/graemlins/cheers.gif" alt="" />

Re: UPDATE: Problem with GenIII (2005) - 03/10/14 11:42 AM

No, I'm still running with multiple warning lights. Mostly now it is service engine soon, and both the traction control indicators lit. Seems like when I'm on the road for an hour or more, then the rear drive indicator lights go out, and the front diff light blinks. It is running well, and otherwise isn't giving me any trouble. I just don't have the $ to buy a new alt right now, so I'm going to have to cross my fingers and hope it keeps running until I see some daylight.

Another addition to the electrical oddities I'm seeing. I was nearly out of gas yesterday. The dash readout showed that I could drive 38 more miles before running out of gas. I pulled into a gas station and put 20 bucks worth (all I had on me at the moment - no debit/credit cards as I'm in the divorce process) and the mileage didn't change on the dash readout. It kept counting down from 38 until it was blinking 0. At some point it stopped doing that, and now it just shows a blank field where the miles remaining would be displayed. Probably not related to my other issues, but thought I'd throw it out there just in case.

Thanks Phil. It's a tough time for me, but I'm trying to stay positive, and keep in mind how many things I have to be thankful for. The only complaint I could make about my entire life is that I married a crazy woman 14 years ago (self-inflicted wound). LOL Kids and family are healthy, life is good. <img src="/forums/images/graemlins/cheers.gif" alt="" />

Car-Part lists a number of alternators available pretty cheap. May get you past this bump in the road anyways.

I'm seeing them from $35 up. May be worth checking out? <img src="/forums/images/graemlins/kewl.gif" alt="" /> <img src="/forums/images/graemlins/cheers.gif" alt="" />
