Today while driving on the freeway I heard a tone and then these indicator lights on the dash started flashing:
Electonic Throttle Control (ETC) warning light
Electronic Stability Program (ESP) Indicator light

I pulled over and shifted to Park and I noticed a high idle. Then I turned the engine off and retarted. After restart, it was idling normal and these warning lights disappeared. I checked for codes as mentioned in another thread and only saw ----- done. Any thoughts before a take it to the dealer?

 

I guess my question is - has anyone ever had this issue and what was the outcome? I wonder if I should wait and see if it happens again or if it could be a major issue and need to get it check out right away? I hope I don't have to pay the dealership $100 for a diagnostic so they can tell me they just cleared a code. BTW, I just bought my Jeep from them about a month ago.

 

Personally I would not worry about it unless it comes back.

The Jk's ecu can be a bit buggy sometimes.

 

This happened once to my '10. I was at a red light, started moving, and both lights came on after a sudden lurch. I pulled over and restarted the engine, neither light came back on and have yet to have a repeated issue. I had taken it to the stealership and they could not pull a code on it.

 

I think I'll do that. thanks

 

so I won't worry about it then and hope I dont see it anymore. So far it has not come back. I want to avoid taking it to the stealership unless I have to. Thanks a lot for your reply.

 

I had that happen in my 2010, back in November 2009, just after I bought it. Happened maybe three times, and hasnt returned.

 

I had this exact issue happen. Thankfully, mine happened right after I bought it brand new. It had these two codes:

P0507 - Idle Speed Performance Higher Than Expected
P061a - Etc Level 2 Torque Performance

They installed a copilot system on the car to see what it was doing when it happened, but the system didn't record anything. They did replace a pcv valve a few days ago and we're waiting to see if this was the right fix.

 

Just had this happen to me. Any of the original posters have any follow-up info?

 

This happened to me today too. Just had my Jeep in to have the front fender liners trimmed and the gas tank looked at for over spilling. I doubt this has anything to do with it. I shut off the Jeep and restarted. It was still there. So I turned off the Jeep, got out and looked at the owners manual on the side of the road for maybe 5 minutes. I got back in, started up, and it was still happening. As soon as I shifted it into drive (automatic) and stepped on the gas it went away. Hasn't happened since. Strange.
