Transmission Temperature Sensor/Switch: Service and Repair

ATF Temperature Sensor Test/Replacement

1. Raise the vehicle on a lift, or apply the parking brake, block both rear wheels, and raise the front of the vehicle. Make sure it is securely supported.

2. Remove the engine under cover Engine Undercover Replacement.

3. Disconnect the shift solenoid wire harness connector.






4. Measure the ATF temperature sensor resistance between shift solenoid wire harness connector terminals No. 5 and No. 6.





- If the resistance is within the standard, the test is complete, reconnect the connector, then install the engine under cover.
- If the resistance is out of the standard, go to step 5.

5. Remove the drain plug (A), and drain the ATF.





6. Reinstall the drain plug with a new sealing washer (B).

7. Remove the left front wheel.

8. Remove the shift solenoid valve cover (A), the dowel pins (B), and the gasket (C).






9. Remove the shift solenoid wire harness (A).






10. Disconnect the connectors from the shift solenoid valves. Then replace the ATF temperature sensor and the O-ring (F) with new ones.

NOTE: The ATF temperature sensor is not available separately from the shift solenoid wire harness (G).





11. Connect the shift solenoid valve connectors:

- BLU wire connector to shift solenoid valve A.
- ORN wire connector to shift solenoid valve B.
- GRN wire connector to shift solenoid valve C.
- YEL, WHT, and WHT wire connector to shift solenoid valve D.
- RED wire connector to shift solenoid valve E.

12. Install a new gasket, the dowel pins, and the shift solenoid valve cover.

13. Check the connector for corrosion, dirt, or oil, and clean or repair if necessary, then connect the connector securely.

14. Refill the transmission with ATF.

15. Install the engine under cover Engine Undercover Replacement.

16. Install the left front wheel.
