Q: What does code P0227 mean?

Throttle/Pedal Position Sensor/Switch 'C' Circuit Low. P0227 means the engine computer has detected a low-voltage condition on the signal circuit for throttle or pedal position sensor 'C', which is often the second track inside the accelerator pedal assembly. The computer expects a voltage that rises and falls with pedal movement, and it has seen the 'C' circuit stay below the acceptable minimum for the current throttle angle.
