This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer is getting a signal that says the car is in park or neutral, but the signal is too strong or too high. It's like when you turn the volume up too loud on a radio.
The P0852 code is triggered when the powertrain control module (PCM) detects a high voltage signal from the park/neutral switch circuit.
The park/neutral position switch is responsible for informing the vehicle's computer about the gear position. When the switch sends a voltage signal that is higher than expected, the PCM sets the P0852 code. This can affect the vehicle's ability to start or operate properly.
• Check Engine Light is on
• Vehicle may not start
• Transmission issues
• Faulty park/neutral position switch
• Wiring issues such as short circuits
• Faulty PCM
PCM: Powertrain Control Module
OBD-II: On-Board Diagnostics II
• Scan the vehicle for codes and freeze frame data.
• Inspect the park/neutral position switch and wiring for damage.
• Test the voltage at the park/neutral position switch.
• Replace the park/neutral position switch if faulty.
• Repair or replace damaged wiring or connectors.
• Reprogram or replace the PCM if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Ford F-150
• Chevrolet Silverado
• Toyota Camry
• Regularly inspect wiring and connectors.
• Avoid exposure to moisture and corrosion.
• Perform routine maintenance checks.
Sensor Issue
• Do not ignore the Check Engine Light.
• Have the vehicle checked by a professional.
• Avoid driving if the vehicle is not starting properly.
Check with the vehicle manufacturer for warranty coverage on electrical components.
P0852 has been a common code for vehicles with automatic transmissions, often related to sensor or wiring issues.
Moderate – It may affect vehicle starting and operation, so it should be addressed soon.
Ignoring this code may lead to unsafe driving conditions. Always ensure your vehicle is in proper working order.
• Vehicle in Park or Neutral
• Engine off
The park/neutral position switch is typically located on the transmission or near the gear selector.
Q: Can I drive with a P0852 code?
A: It's not recommended as it may affect the vehicle's ability to start or operate properly.
Q: What happens if I ignore the P0852 code?
A: Ignoring this code can lead to starting issues and potential transmission problems.
