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 as dirt or
debris can cause issues.
•
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.
