- Faulty accelerator pedal position sensor
- Wiring or connector issues in the sensor circuit
- Corrosion or damage to sensor components
- ECM software or hardware problems
- Electrical issues such as a short circuit or open circuit in the sensor circuit
Symptoms of P2122 2017 Chevrolet Silverado
- Hesitation or lack of response when pressing the accelerator pedal
- Rough idling or unstable engine RPM
