Transaxle Fluid Temperature (TFT) Sensor Inspection

TRANSAXLE FLUID TEMPERATURE (TFT) SENSOR INSPECTION [AW6A-EL]

On-Vehicle Inspection

Caution
^ Water or foreign material entering the connector can cause a poor connection or corrosion. Be sure not to allow water or foreign material on the connector when disconnecting.
^ Do not damage the terminals.

1. Disconnect the negative battery cable.
2. Remove the air cleaner component.
3. Remove the TCM.





4. Verify that there is no continuity between coupler component terminals B7 and GND, or B8 and GND.
^ If there is any malfunction, perform an off-vehicle inspection of TFT sensor. (See Off-Vehicle Inspection.)
5. Install the TCM.
6. Install the air cleaner component.
7. Connect the negative battery cable.

Off-Vehicle Inspection

Warning
^ A hot transaxle and ATF can cause severe burns. Turn off the engine and wait until they are cool before replacing the ATF.

Caution
^ Water or foreign material entering the connector can cause a poor connection or corrosion. Be sure not to allow water or foreign material on the connector when disconnecting.
^ Do not damage the terminals.

1. Disconnect the negative battery cable.
2. Remove the air cleaner component and air cleaner bracket.
3. Place the heater pipe out of the way.
4. Remove the under cover.
5. Set the mudguard in a location out of the way. (front LH)
6. Remove the splash shield. (front LH)
7. Drain the ATF.
8. Remove the oil hose, oil pipe and O-ring.
9. Remove the control valve body.
10. Remove the TFT sensor.
11. Place the TFT sensor and a thermometer in ATF as shown in the figure, and heat the ATF gradually.





12. Measure the resistance between the coupler component terminals B7 and B8.
^ If there is any malfunction, replace the TFT sensor.
