Code P0852 Chrysler Description
The P0852 code for Chrysler vehicles indicates a problem with the Park/Neutral Position (PNP) switch circuit, specifically signaling a high voltage issue. The PNP switch is an essential component of the vehicle's transmission system that communicates the position of the gear selector (Park, Neutral, Drive, Reverse) to the engine control module (ECM). When the ECM detects a high voltage reading from the PNP switch circuit, it means that there is an electrical fault or malfunction in the circuit that could potentially disrupt the proper operation of the transmission system.
Common Causes of P0852 Chrysler
- Faulty PNP switch
- Corroded or damaged wiring in the PNP switch circuit
- Loose or poor electrical connections
- ECM malfunction or software issue
- Water or debris ingress in the switch connector
Symptoms of P0852 Chrysler
- Difficulty starting the vehicle
- Inability to shift out of Park
- Erratic transmission shifting
- Check Engine Light illuminated
- Engine stalling or rough idling
How to Fix P0852 Chrysler
- Begin by conducting a thorough diagnosis with a scan tool to confirm the P0852 code and pinpoint the exact cause of the high voltage condition.
