TPMS

DTC 21, 22, 23, 24: Tire Pressure Sensor Abnormally High Temperature

1. Make sure the tires have cooled down.
2. Turn the ignition switch ON (II).
3. Check the tire indicated by the DTCs you retrieved.

NOTE: An abnormal rise in the internal temperature of the tires can be caused by:
^ Excessive braking
^ Failure to release the parking brake (rear tires only)
^ Leaving the vehicle running while parked
^ Improper assembly of a wheel and tire





4. Turn the ignition switch ON (II).

Does the TPMS indicator go off within 1 minute?

YES - The system is OK at this time. Clear the DTC with the HDS.

NO - Go to step 5.

5. Read the internal temperature of the tire with the HDS.

NOTE: If the HDS screen shows UNDEFINED for sensor status, turn the ignition switch OFF, rotate the tire 1/4 turn, then turn the ignition switch ON (II), and try again. If UNDEFINED is still shown, repeat the rotating procedure until NORMAL is shown.

Is 176°F (80°C) or more indicated?

YES - Replace the appropriate tire pressure sensor.

NO - Check for loose terminals and poor connections at the TPMS control unit. If necessary, substitute a known-good TPMS control unit, and recheck.
