Code P2176 And P2135
I have a 2007 Cobalt SS, I started with only a code for P2135 which is TPS Sensor Voltage Correlation DTC. I did some research and I just replaced the entire throttle body assembly. Drove fine for a day and a half then stopped at a gas station turn on car it went into limp mode with 2 codes the P2176 ( Throttle actuator control system - Idle position not learned ) and P2135. I dont know where to start looking for the problem. I have people telling me i should re flash my ECU or check for a problem with the wiring, or the Pedal position sensor could be bad. If anyone has had this problem before where should I start? This is my daily so its pretty hard getting to work because i cant drive it.
