Crown Victoria Severe Duty Each road tire, as well as the spare, is equipped with a tire pressure sensor fastened to the inside of the rim, opposite (180 degrees) from the valve stem. The signal from each transmitter is digitally unique to avoid interference from transmitters on other nearby vehicles. Note: The spare has a TPMS sensor, but is not programmed to the module. Changing tires with a TPMS Care should be taken avoid damaging the sensor and band during mounting or dismounting. Please refer to the Crown Victoria Workshop Manual for the complete mount and dismount procedure. This is critical, as the procedure is different from previous model years due to the introduction of TPMS. When a new tire/wheel is installed When one of your road tires is replaced by a new tire/wheel, the TPMS sensor located in the new tire/wheel needs to be "trained" to the vehicle. TPMS system training tools An inexpensive TPMS training tool, P/N 8C2Z-1A203-A, can be purchased from any Ford dealer for use by the driver or shop technician for training the system after maintenance has been performed that requires system training. The Tire Pressure Monitor Activation Tool, P/N 204-363, has more functionality and is designed primarily for shop use. For either tool, follow the training instructions as outlined below. Note: This procedure is also included in the Crown Victoria Workshop Manual. 275 2011 Crown Victoria (cro) Owners Guide, 1st Printing USA (fus)
