Limp mode on a manual

Hope this all works out for you, I know how frustrating these issues can be. And as always keep us posted.

Thank you for the kind words.

Certainly shall do on updates.

This morning, I went and double checked the battery terminals. I opted not to dig into the grounds as frankly I was intimidated by the degree of work necessary to reach that part of the engine.

Went for a drive on the same offending road as yesterday. After about 4 miles of washboard, the CEL and ESC lights came on again. Engine rpm drop again at 3k.



The "key dance" does not display any code. Tried a couple of sequences.

I suppose on the bright side I eliminated the battery terminals as a causal factor. I did check that they were still tight.

I have not reset the computer, and am not sure if I should. If I do, will I lose the history of the CEL events?

I have a service appointment scheduled for 7/18/14.

Yeah don't clear it this time. Hopefully they will delve further than simply replacing a cam sensor that is probably fine.

Got it.

Thank you again for all your help!

No problem, sorry it wasn't much help. Hopefully it gets taken care of.

Some weirdness:

So, I start up the jeep this morning. CEL light on, but ESC is off. The jeep exhibited this during the first occurrence. On engine start, only CEL displays, and the ESC will illuminate at some point later, seemingly after a jar or bump in the road.

Anyhow, drive to the gym, and about an hour later, I start the jeep again, and no CEL display.

This has not happened before. That is, once active the CEL stayed illuminated at all times.

Updates:

1. All error lamps have been off since my last post above.

2. I went to the dealer today, and they could not find any problems at all. They read the codes, but tell me that components checked out ok. They also told me that they checked grounds and the wheel position sensor.

3. I had a long, but not confrontational, discussion with my service advisor. He seems sympathetic to the problem, and I prefer not to poison my relationship with him. Anyhow, next step is to see if the error lamps display again, and then leave the jeep for an extended period.

4. Driving home, I (of course) drove down the gravel road (referenced above), and of course, no error lamps.

I am thinking that my next action will be to take a local easy trail this weekend, and see if that will trigger the problem.

Update:

3.5 miles down an easy trail and I am back to square one ...

No code was displayed when I did the key dance.

I will try to get in to the dealer tomorrow or Tuesday.

Sorry you are having such issues. This would drive me crazy.

I'm still convinced of a loose connection.

Thanks; and, yes, this is making me a bit bonkers.

BTW, this afternoon, all error lamps are off again.

The intermittent nature of this problem concerns me. Will the dealer simply do another cursory check, and say it's okay. Doubt that the dealer will actually bother to take it on a dirt road, and then if they do, the problem may not occur. I suppose lemon-law criteria is my leverage to convince the dealer not shrug this off. But, this is becoming a PITA.

See if one of the service guys will go with u to recreate the problem?

Jeez, that is so strange. Are you taking pictures when the CEL is on? If not, start so you at least have some evidence if you end up wanting to pursue a lemon case. It does seem like something must be loose. Sorry you're still dealing with this!

Great idea! Maybe even setup a video camera to record the dash while you're driving over the area where you experience it.

That may work. Good idea. Thanks!

My wife suggested the same. Great minds ...

Another good idea. Good project for my 11 yo. Thanks!

Jeep is at the dealer.

Dealer confirmed that they can read codes that seem to "self clear".

Dealer provided me with a loaner, which they did not have to do. So, I have to commend that.

Hope they figure it out and it's an easy fix!

Just got a call from my dealer, and they replaced the cam position sensor again.

The service advisor agreed with my skepticism that two cam position sensors from two different sources (factory and dealer) would both be bad, so they will keep the jeep for a more thorough test on rutted washboard type road, assuming they can find one close by ... which, this being Phoenix should not be too hard, I hope.

That would be quite a fluke unless something is making the sensor go bad....if that's even possible.
