Tribute 4WD L4-2.3L Hybrid (2008)
Tire Pressure Sensor: Description and Operation
TPMS PRESSURE SENSOR
The TPMS monitors the air pressure in the 4 road tires with tire pressure sensors. The sensors transmit radio frequency (RF) signals to the SJB
approximately every 60 seconds when the vehicle speed exceeds 32 km/h (20 mph).
The tire pressure sensors are battery operated and are mounted to metal brackets (called cradles) on the wheels inside the tires. The sensors are mounted
180 degrees from the valve stem. The tire pressure sensor can be serviced separately from the cradle and the strap.
TPMS PRESSURE SENSOR CRADLE
The tire pressure sensor cradles are mounted to the wheels with metal straps and have an adhesive strip to aid in their retention to the wheel.
To service the sensor cradle, the strap must also be removed.
TPMS PRESSURE SENSOR STRAP
The sensor strap is what keeps the sensor and the cradle retained to the wheel. A factory-installed strap is joined together with a one-time use buckle and
a dealer-installed strap is joined together with a worm gear (similar to a radiator hose clamp). Both straps should be discarded after removal and should
not be reused.
The strap can be serviced separately from the sensor and the cradle. The sensor is available separately from the cradle and the strap. The cradle and strap
are available as a strap kit. There are several different strap kits available based on wheel diameter but all strap kits share the same base part number.
