NOTICE

Ensure the proper direction of the tire pressure warning system valve & transmitter by adhering to
the prescribed procedure for installing a tire pressure warning system valve & transmitter on a wheel.
Failure to do so could result in an incorrect measurement of the tire air inflation pressure.

Make sure to replace the tires in accordance with the prescribed procedure. To prevent the tire pressure
warning system valve & transmitter from damage, drop the tire pressure warning system valve &
transmitter into the wheel before removing the tire. Failure to do so could damage the tire pressure
warning system valve & transmitter.

For further details regarding the above, see the 2007 Camry Hybrid Vehicle Repair Manual (Pub. No
RM02H0U).

Service Tip

If the lithium battery is depleted, replace the entire tire pressure warning system valve & transmitter
assembly.

After a tire pressure warning system valve & transmitter has been replaced, the ID of the tire pressure
warning system valve & transmitter must be registered in the ECU. To register an ID, use a hand-held
tester to enter the ID code that is indicated on the sensor.

When replacing the tire pressure warning system valve & transmitter, all the separate ID codes of the
4-tire pressure warning system valve & transmitter must be registered. Even if only 1 tire pressure
warning system valve & transmitter is replaced, the ID codes of all 4 tire pressure warning valve &
transmitter must be registered again.

A new tire pressure warning system valve & transmitter that is available as a service part is in the sleep
mode in its initial state, to prevent the battery from depleting. During PDS (Pre-Delivery Service),
after the tire pressure warning system valve & transmitter and the tire are correctly mounted on the
disc wheel, inflating the tire to the specified pressure causes the sleep mode to cancel.

For further details regarding the above, see the 2007 Camry Hybrid Vehicle Repair Manual (Pub. No.
RM02H0U).

CONSTRUCTION AND OPERATION

1. Tire Pressure Warning System Valve & Transmitter

The tire pressure warning system valve & transmitter is integrated in the air valve of a disc wheel. It
measures the pressure and the temperature of the air in the tire and transmits the measured values and a
recognition ID to the tire pressure warning system valve & transmitter.

If the battery voltage drops, the tire pressure warning system valve & transmitter assembly must be
replaced. Furthermore, if the battery voltage drops, the tire pressure warning system valve & transmitter
will be unable to transmit signals, which causes a DTC to be output.

Tire pressure warning system valve & transmitter with 4 different ID code range are used on one vehicle.

Each tire pressure warning system valve & transmitter has a built-in semi-conductor to directly measure
the inflation pressure of the tire.

Frequency of the tire pressure warning system valve & transmitter is 314.98 MHz.
