Help "Reduced Engine Power"
I have a 2001 Z06 with a H/C package, Kooks headers and 4:10 gears. Last Friday night while racing my car, it went into a reduced engine power mode immediately following my shift to second gear. The codes are PCM10 P1221H and TCS 1278H. This happened 3 times that night. I drove the car home and the condition did not re-appear until this morning, while driving to work. I was able to reset it and continued my drive to work as normal. When I started my car after getting out of work, the "reduced Engine Power" was displaying with my engine light on again. The traction control indicated in the off mode without me touching the button. When I attempted to turn the Traction control on, it had no effect. I believe the TCS 1227 Engine code has something to do with traction control. Not sure why and I am not sure why the P1221H code was activated. There was nothing recently done to the car. Last fall is when the gears were replaced. The H/C package and exhaust was done 2 years ago. Any help would be much appreciated. Just for your info., the car ran a 11.36 @ 124.4 mph at a 1.70 60 ft. about 2 months ago.
