Code P2135 2015 Chevrolet Silverado Description
The P2135 diagnostic trouble code (DTC) for a 2015 Chevrolet Silverado indicates that there is a discrepancy between the signals from throttle position sensors 1 and 2, leading to a "Not Plausible" reading. In simpler terms, this means that the Engine Control Module (ECM) is receiving conflicting data from the two throttle position sensors, which are responsible for monitoring the position of the throttle pedal and sending this information to the ECM. This discrepancy can lead to issues with engine performance, fuel efficiency, and overall drivability of the vehicle.
Common Causes of P2135 2015 Chevrolet Silverado
- Faulty throttle position sensors
- Damaged wiring or connectors
- Corrosion or poor connections in the sensor circuit
- ECM software issues
