Tire Pressure Sensor: Description and Operation
Tire Pressure Monitoring (TPM) Sensor - Operation
OPERATION
CAUTION: The TPMS has been optimized for the original equipment tires and wheels. TPMS pressures have been established for the tire size
equipped on your vehicle. Undesirable system operation or sensor damage may result when using replacement equipment that is
not of the same size, type, and/or style. After-market wheels can cause sensor damage. Do not use aftermarket tire sealants or
balance beads if your vehicle is equipped with a TPMS, as damage to the sensors may result.
CAUTION: After inspecting or adjusting the tire pressure always reinstall the valve stem cap. This will prevent moisture and dirt from
entering the valve stem, which could damage the Tire Pressure Monitoring Sensor.
CAUTION: Tire pressure sensor valve stem caps and cores are specially designed for the sensors. Due to risk of corrosion, do not use a
standard valve stem cap or core in a tire pressure sensor in place of the original equipment style sensor cap and core.
CAUTION: Any time a sensor is to be reinstalled in a wheel, a new valve stem assembly must be installed to ensure air tight sealing.
NOTE: TPM thresholds have been established for the original tire size equipped on the vehicle. Use original size tires only to maintain system
accuracy.
The battery operated tire pressure sensor is both a transmitter and a receiver. The TPM sensor can be forced to transmit if using a special tool such as a
TPM-RKE Analyzer. The TPM-RKE Analyzer has the ability to change the sensor mode and to diagnose a faulty TPM sensor. Using a TPM-RKE
Analyzer can take up to a minute to force a transmission from a sensor.
Each sensor's (transmitter) broadcast is uniquely coded so that the module can monitor the state of each of the sensors on the four rotating road wheels.
The module can automatically learn and store the sensor's ID while driving "within 10 minutes continuously above 15 m.p.h. (24 Km/h)" after a sensor
has been replaced. The vehicle must be stationary for more then 20 minutes in order to initiate the learning sequence.
The sensor IDs can also be programmed using the TPM-RKE Analyzer Tool. Scan each TPM sensor at each road wheel, and store each Sensor ID in the
correct location. (LEFT FRONT, LEFT REAR, RIGHT FRONT, and RIGHT REAR) Connect the TPM-RKE Analyzer Tool to the Scan Tool. Then
follow the programming steps outlined in the diagnostic Scan Tool for "Program Tire Pressure Sensor ID w/ TPM Tool".
