Ensure there are no obstructions such as dirt, ice, or debris that may affect their operation.

3. Inspect and Repair Wiring

Remove any protective coverings to access the wiring harness connected to the sensors.
Check for frayed wires or loose connections.
If any damage is found, repair or replace the affected wiring using electrical tape or heat-shrink tubing.

4. Replace Faulty Sensors

If any sensor is found defective during testing, replace it:
1. Remove the defective sensor by gently twisting and pulling it out from its housing.
2. Disconnect the wiring harness from the old sensor.
3. Connect the new sensor, ensuring a secure fit.
4. Reinsert the new sensor into its housing.

5. Reassemble and Test

Reconnect any removed protective coverings and the vehicle’s battery.
Start the vehicle and engage the reverse gear.
Test the operation of the parking sensors to ensure they are functioning correctly.
