Default 08 Impala Code P2127
I had a reduced engine power warning on my dash board. I read the code and it said P2127 Throttle/Pedal position sensor/switch e circuit low. I’ve read it could be the gas pedal or the throttle position sensor under the hood. I’ve had the reduced engine power before and replace the gas pedal about 10 years ago. Seemed fine until now. Do you think it is that again?
