DTC 32, 34, 36, 38 : Tire Pressure Sensor Signal Failure

NOTE:
* Inspect for an aftermarket electrical device(s) (such as an inverter, cell phone 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 that DTC first TPMS Control Unit.

1. Wheel check:

Wheel check
-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 2.
-NO- Install a TPMS type wheel, and memorize the tire pressure sensor ID with the HDS Memorizing The Tire Pressure Sensor ID.

2. Tire pressure sensor check 1:

Tire pressure sensor check 1
-1. Turn the ignition switch to ON (II).

-2. Check for DTCs with the HDS.

-3. Note the tire pressure sensor(s) number by the indicated DTC.





-4. 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.

Did each tire pressure sensor respond to the TPMS tool?
-YES- Go to step 3.
-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.

3. Tire pressure sensor check 2:

Tire pressure sensor check 2
-1. Turn the ignition switch to LOCK (0), and wait 5 minutes or more.

-2. Test-drive the vehicle at 28 mph (45 km/h) or more for at least 1 minute.

-3. Check if the values of the AIR PRESSURE and AIR TEMPERATURE of the affected sensor change from DEFAULT to the correct tire pressure on the TPMS DATA LIST with the HDS.

Did the values of the AIR PRESSURE and AIR TEMPERATURE change from DEFAULT to the correct tire pressure?
-YES- Intermittent failure, the system is OK at this time.
-NO- Replace the appropriate tire pressure sensor Service and Repair.
