TPMS Transmitter Check Or Replace

After removing the tire from the wheel, remove the TPMS transmitter (Refer to REMOVAL AND INSTALLATION  ). Then check it as follows and replace if necessary:

1. Wipe off the agent remained on the TPMS transmitter housing. In particular, remove it thoroughly around the pressure detection hole.
   NOTE: Wait for a while to allow the agent to set, and then detach it.
2. If any of the following conditions is found, replace the TPMS transmitter and then register the tire pressure sensor ID code: In addition, replace the valve, the valve core and the cap. Then install the tire assembly to the wheel (Refer to REMOVAL AND INSTALLATION  ).
   • Damage (deformation or scratch, etc.) on the exterior of the housing
   • The agent cannot be removed thoroughly from inside the pressure detection hole.
3. If the conditions above are not found, the TPMS transmitter can be reused. Replace the valve, the valve core and the cap only. Then install the tire assembly to the wheel (Refer to REMOVAL AND INSTALLATION  ).
   NOTE: If the TPMS transmitter is reused, the pressure measurement function should be checked as follows.

   • Inflate the corresponding tire to 250 kPa (36.2 psi) or more, and perform step  2 in the TPMS transmitter check (Refer to TPMS TRANSMITTER CHECK  ).
   • Inflate the corresponding tire to 150 kPa (21.7 psi) or less, and perform step  2 in the TPMS transmitter check (Refer to TPMS TRANSMITTER CHECK  ).

   
   If abnormal pressure difference[20 kPa (2.9 psi) or more] is observed in these checks, replace the TPMS transmitter and register the tire pressure sensor ID code.
