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 the TPMS.
When a new tire/wheel is installed, the TPMS sensor located in the
new tire/wheel needs to be "trained" to the vehicle.
TPMS training tools, such as 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.
