P2136 Throttle/Pedal Position Sensor A/C Voltage Correlation
The "A" and "C" channels of the throttle or pedal sensor disagree by more than the allowed tolerance. The ECU cannot trust either reading and forces limp-home with reduced torque.
Is it safe to drive with P2136?
The car may go into limp mode (reduced power). Get it diagnosed before a long trip.
Common causes
- Most likelyOne sensor track worn
- PossibleConnector corroded with leakage
Symptoms
- Check engine light on
- Reduced throttle response, possible limp mode
- Hesitation or surging
- Idle too high or too low
