- Perform TPM VERIFICATION TEST.

4. INTERMITTENT TIRE PRESSURE SENSOR DTC

NOTE: The DTC can be caused by many different factors and might not be a sensor/transmitter or a TPM Module fault. Interference from other elements will over power the sensor/transmitter RF frequency making erratic operation to the TPM system. Check the vehicle for aftermarket accessories that could compromise the RF frequency signal before diagnosing the TPM system.
