  post locked   2009 Aveo high RPMs, low acceleration  

2009
Chevrolet
Aveo LT
45000miles
(2.0 engine)

As of yesterday, my Aveo's Check Engine light came on and the car itself started driving all bogged down. The car is very slow to get up to even 25mph, while the RPMs are jumping high. I took it to the dealership today and they ran the codes, and told me about an acceleration sensor. Then they called back to say that they believe it to be a bad ground to the accelerator itself. However, they have spent 5 hours now trying to find the bad ground and are unable to do so. CrazyAny other ideas or advice here would be great... this is likely to be quite expensive due to the amount of time in labor.Laugh

Try to find out what specific trouble code they got. Acceleration sensor? Must be a communication error. Poor ground to any sensor can cause a problem, but need more info.

The code on the paperwork is listed as P2138. The tech never found the actual problem, I had to cut off their exploration time when the labor cost hit $400.00. It's running just fine at the moment, but I am scared it will occur again.

talktome; The only thing I could find was a TSB, dated 06/28/10, relating to the sensor 1 & sensor 2 correlation (P2138). The TSB refers to 'Water intrusion into instrument panel to body harness connector, causing out of parameter voltage readings'. The TSB #: 07-06-04-019D.

This car should still be covered under the 5yr/100K drive train warranty. I would contact the dealer.

Hammer is right on the Powertrain Warranty. The problem is probably the throttle body. I have replaced several on this model car at my dealership.

My aveo will get high RPMs but the light doen't come on. It first happen March 20111 as I was pulling into a rest Area, I thought I had pulled next to a tracter. When I turned the engine off my wife asked what the noise was so I turned it back on and it reved up to 4000 rpms while in park. I had noticed that when I pulled in to park and took it out of gear it was rough. Took it to the Chevy dealer and they couldn't find anything and said the engine light should have came on. It didn't.
This March it would happen when I was increasing my on the road. It would reve up but pick up speed very slowly. Real loud, not much power. The dealer still could not find anything.

I reported it too GM last year but they just had me take it into the dealer.
