NOTE:
Always use the correct part for the proper model year and production range, failure to do so may result in vehicles which are difficult to repair and can be subject to warranty chargeback.
^ Excessive aftermarket wiring tie-wrapped and coiled on or near TPMS module. This may create a magnetic field causing concern.
