Code P0852 2017 Chevrolet Silverado Description
The P0852 diagnostic trouble code (DTC) for a 2017 Chevrolet Silverado indicates a problem with the Park/Neutral Position (PNP) switch circuit having high voltage. The PNP switch, also known as the transmission range sensor, is responsible for detecting the gear position of the transmission. When the vehicle is in park or neutral, the PNP switch sends a signal to the engine control module (ECM) to allow the engine to start. If the PNP switch circuit detects high voltage, it means that there is an issue with the electrical connection or the switch itself.
Common Causes of P0852 2017 Chevrolet Silverado
- Faulty Park/Neutral Position (PNP) switch
- Damaged wiring or connectors in the circuit
- Corrosion in the electrical connections
- Malfunctioning Engine Control Module (ECM)
