APPENDIX A. Troubleshooting Vehicle Sensors
Start with a general inspection of the sensor fitment. Check that both
the sensors and the sensor clips are fully secure and the sensors are
properly centered in the housing.
Confirm plastic housing is in the correct mounting holes. Misplaced
sensor housings could compress sensor and give false readings or
faults.
Use a clean microfiber to wipe the front face of the sensor.
Inspect connection. Be sure that the sensor is firmly seated into the
harness.
Run through several start cycles (i.e. fully turn the vehicle on and off).
Finally, disconnect the battery to reset the sensors.
If sensors still do not work, sensors may have been
damaged during the installation process. Take vehicle
to a certified dealership.
