The throttle position sensors are responsible for monitoring the position of the throttle pedal and communicating this information to the engine control module (ECM) to adjust fuel delivery and engine performance accordingly.
Common Causes of P2135 2016 Chevrolet Silverado
- Dirty or damaged throttle position sensors
- Faulty wiring or connectors related to the throttle position sensors
- Incorrect sensor calibration
- Malfunctioning ECM or software issues
- Water or corrosion damage to sensor components
