TRANSAXLE FLUID TEMPERATURE (TFT) SENSOR INSPECTION [GF4AX-EL]

id0517a4801000

On-Vehicle Inspection

1. Disconnect the negative battery cable.

2. Remove the battery and battery tray.

3. Remove the air cleaner component. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [L3].)

4. Disconnect the coupler component connector.

5. Measure the resistance between the terminals of the TFT sensor.

• If there is any malfunction, perform the off-vehicle inspection of TFT sensor. (See Off-Vehicle Inspection.)

6. Connect the coupler component connector.

7. Install the air cleaner component. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [L3].)

8. Install the battery tray and battery.

9. Connect the negative battery cable.

Off-Vehicle Inspection

1. Remove the TFT sensor. (See TRANSAXLE FLUID TEMPERATURE (TFT) SENSOR REMOVAL/INSTALLATION [GF4AX-EL].)

2. Place the TFT sensor and in ATF a thermometer as shown in the figure, and heat the ATF gradually.

3. Measure the resistance between the terminals of the TFT sensor.

• If there is any malfunction, replace the TFT sensor. (See TRANSAXLE FLUID TEMPERATURE (TFT) SENSOR REMOVAL/INSTALLATION [GF4AX-EL].)
• If it is normal, replace the harness.
