Reduced Power, TC/Stability Disabled, Not running on all Cylinders - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

UNVME2012 · 07-15-2012, 08:42 PM

I had a serious problem with my 2012 Camaro 2SS. I was driving on the hwy about 75mph....AND all of a sudden my display says "Reduced Power" my engine light comes on, my ABS turns off and I have absolutely no power and had to pull over along side of the hwy. The motor was running very rough...not on all cylinders. Luckily I had my Diablo Predator tuner in the car and I hooked it up and the following DTC failures showed. 1-Crank case sensor, 2-Throttle pedal sensor and 3-Voltage sensor B circuit/open. I reprogrammed the computer and erased the codes and it started right up. However, I started driving again and when I went to pass someone with slight accelleration it happened again. AGAIN! I had to pull over along side of the hwy and reset the DTC codes. I had to baby the throttle in order to make it home. I have no clue what the hell is going on with my car... I am taking it to the dealership tomorrow! Monday, July 16th to get it checked out.. Hopefully I will make it to the dealership without any problems. I use only 93 octane fuel and last fill up was at mobile gas station... Any one have any problems like this before???? Please let me know.

Did you do anything to the car??

did you check the spark plug wires..

the dealership will figure it out but sounds like bad gas or somthing happened to the wires

or maybe the throttle body plug came lose....

Please let us know the official diagnosis from your local dealership and if they were able to correct the issue. I apologize for any frustration or inconveniences you experienced with this.

I had somthing real close. Turned out the wiring harness for the crank shaft positioning sensor needed to be replaced. If it turns out to be that and they tell it's all fixed and your ready to go, you'll probabably get another engine light and then you'll need new cadalytic converters because of the fuel that dumped through your exhaust.

:(The problem just happen to me Today. I am searching now for possible causes now on Camaro5. I stopped at a stop sign and heard a single pop, then all the lights came on. Power was reduced and the car sounds as if it is not operating on all cylinders. Check engine light and all the "Stability" Icons are on. (I have a LS3)

I don't mean to thread jack but, I forgot how to start a thread.(sorry - I'm kind of feeling low right now)

Mr. Brandon of Chevrolet Customer Service, what advise can you give me to help the dealership solve my problem.
