Toyota scan tool needed to register Camry IDs
Note transmitter ID when replacing Camry valve sub-assemblies

SUBJECT VEHICLE: 2007-10 Toyota Camry.
SENSOR IN TIRE? No, the TPMS sensors are mounted in the wheels.
RESET PROCEDURE? Yes. Directions follow.
SPECIAL TOOLS NEEDED? Yes, a hand-held tester.
The tire pressure monitoring system (TPMS) on the Toyota Camry model years 2007-10 is designed with a TPM valve sub-assembly. The sub-assembly contains a tire pressure sensor/transmitter installed in each tire/wheel assembly.
The sensor measures the internal tire pressure and temperature. These measured values and transmitter IDs are transmitted to the tire pressure monitor receiver assembly on the body via radio waves. This data is then sent to the tire pressure monitor electronic control unit (ECU) from the tire pressure monitor receiver.
To remove an old sensor and install a new one, follow these steps.
Demount the tire from the wheel using the tire changer manufacturer’s instructions.
NOTE: When a tire, wheel, tire pressure sensor and/or tire pressure monitor ECU are replaced, the sensor ID must be memorized by the tire pressure monitor ECU.
If the tire pressure valve sub-assembly is going to be replaced, make a note of the seven-digit number (transmitter ID) before installation. It cannot be seen after the sensor is installed.
Whenever a new sensor is installed, it will need to be registered in the tire pressure monitor ECU.
1. When replacing a wheel or tire, tire pressure sensors must be set up in one of the following ways:
a. Remove the sensor from the old wheel and install it in the new wheel.
b. Keep the tire pressure sensor mounted in the wheel, and replace only the tire.
c. Use a new wheel and sensor.
2. Remove the wheel. Next remove the cap and valve core, and release the air from the tire (see Figure 1). NOTE: Keep the removed cap, valve core, nut and washer for re-use.
3. After ensuring that air is sufficiently released, remove the nut and washer that is used to hold the tire pressure monitor valve sub-assembly and drop the sensor inside the tire. NOTE: Be careful not to damage the tire pressure monitor valve sub-assembly by allowing it to get between the tire bead and the wheel or shoe during demounting.
4. After dropping the tire pressure monitor valve sub-assembly into the tire, disengage the bead using the shoe of the tire remover.
5. Remove the tire bead on the upper side following the usual removal procedure.
6. Take out the sensor from the tire, and remove the bead on the lower side following the usual procedure. NOTE: Check that no cracks or damage are visible on the grommet. If so, replace the grommet together with the washer and nut. When disposing of the sensor, remove the battery and dispose of properly.
7. Remove the inner grommet from the tire pressure monitor valve sub-assembly, or retrieve from the wheel, if necessary.
