PLC 328017.31 – B90 Park Lock Pressure Sensor, Voltage Too Low
PLC 328017.31 (PLC )
Code: 328017.31
Shortcode:
Description:
This diagnostic trouble code is triggered when the control unit detects a voltage of less than 0.3 volts at the signal input for the park lock pressure sensor (B90). This indicates that the circuit is shorted to ground or is open.
Reaction:
The park lock system may not function correctly, potentially compromising the vehicle’s ability to stay securely parked.
Recommendations:
- Inspect Wiring and Connections:
- Check for any signs of damage, corrosion, or loose connections in the wiring to the B90 park lock pressure sensor. Repair or replace as necessary.
- Test the Sensor:
- Verify the functionality of the B90 park lock pressure sensor. Replace if found to be faulty.
- Check for Shorts to Ground:
- Inspect the circuit for any potential shorts to ground and rectify any issues found.
- Verify Power Supply:
- Ensure that the power supply to the sensor is stable and within the specified voltage range.
Note:
Regular inspections and maintenance can prevent issues with low voltage in sensor circuits, ensuring the reliable operation of safety-critical systems like the park lock mechanism.
