Tire Pressure Sensor Signal Failure

NOTE:

- Inspect for an aftermarket electrical device(s) (such as an inverter, battery charger, CB radio, etc) interfering with the RF signal from the tire pressure sensors when driving the vehicle.
- If DTC 41 is also set, troubleshoot the DTC first 41.

1. Turn the ignition switch to LOCK (0).

2. Make sure all four wheels are TPMS type wheels with mounted tire pressure sensors.

Are TPMS type wheels with a tire pressure sensor mounted on the vehicle?

YES -

Go to step 3.

NO -

Install a TPMS type wheel, and memorize the tire pressure sensor ID with the HDS Memorizing The Tire Pressure Sensor ID (USA).�

3. Turn the ignition switch to ON (II).

4. Check for DTCs with the HDS.

5. Note the tire pressure sensor(s) number by the indicated DTC.





6. Do the tire pressure sensor location procedure to determine the affected tire location and relate it to the tire pressure sensor number Tire Pressure Sensor Location (USA).

Did each tire pressure sensor respond to the TPMS tool?

YES -

Go to step 7.

NO -

Check for an aftermarket electrical device interfering with the RF signals from the sensors. If there are no electrical devices causing interference, replace the appropriate tire pressure sensor Service and Repair.�

7. Turn the ignition switch to LOCK (0), and wait 5 minutes more.

8. Test-drive the vehicle at 28 mph (45 km/h) or more for at least 1 minute.

9. Check if the value of the AIR PRESSURE and AIR TEMPERATURE of the affected sensor changes from DEFAULT to the correct tire pressure on the TPMS DATA LIST with the HDS.

Does the value of the AIR PRESSURE and AIR TEMPERATURE change from DEFAULT to the correct tire pressure?

YES -

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

NO -

Replace the appropriate tire pressure sensor Service and Repair.�
