Code B1752 Description
The B1752 diagnostic trouble code (DTC) indicates a Park/Neutral Switch Circuit Short To Ground. This means that there is an electrical issue in the circuit that controls the park/neutral switch in the vehicle. The park/neutral switch, also known as the transmission range sensor, is responsible for detecting the position of the gear shift lever. When the vehicle is in park or neutral, the switch sends a signal to the engine control module (ECM) to allow the engine to start.
Common Causes of B1752
- Faulty park/neutral switch
- Short circuit in the wiring harness
- Corrosion or damage to the electrical connectors
- Issues with the ECM or transmission control module (TCM)
- Water or moisture intrusion in the switch circuit
Symptoms of B1752
- Difficulty starting the vehicle
- Engine stalling when shifting gears
- Inability to shift into park or neutral
- Incorrect gear display on the dashboard
- Check engine light illuminated on the dashboard
How to Fix B1752
- Begin by diagnosing the exact cause of the short to ground in the park/neutral switch circuit using a multimeter and wiring diagram.
- Inspect the park/neutral switch for any signs of damage or malfunction and replace if necessary.
- Check the wiring harness for any visible damage, corrosion, or loose connections. Repair or replace any damaged wiring.
- Inspect the electrical connectors for corrosion or poor connections. Clean or replace connectors as needed.
- Clear the DTC from the vehicle's ECM memory using a scan tool and test the vehicle to ensure that the issue has been resolved.
