Transmission Temperature Sensor/Switch: Testing and Inspection
ATF Temperature Sensor Test/Replacement1. Raise the vehicle on a lift, or apply the parking brake, block the rear wheels, and raise the front of the vehicle. Make sure it is securely supported.
2. Remove the left front wheel.
3. Remove the splash shield.
4. Remove the drain plug (A), and drain the automatic transmission fluid (ATF).
5. Reinstall the drain plug with a new sealing washer (B).
6. Remove the shift solenoid valve cover (A), the dowel pins (B), and the gasket (C).
7. Disconnect the shift solenoid harness connector, and remove the shift solenoid wire harness from the transmission housing.
8. Measure the ATF temperature sensor resistance between shift solenoid harness connector terminals No. 6 and No. 7.
Standard: 50 ohms - 25 kOhms
9. If the resistance is out of standard, replace the ATF temperature sensor and the shift solenoid wire harness; go to step 10. The ATF temperature sensor is not available separately from the shift solenoid wire harness. If the resistance is within the standard, install the shift solenoid wire harness with a new O-ring in the transmission housing, then go to step 13.
10. Disconnect the connectors from the shift solenoid valves, and replace the ATF temperature sensor and the shift solenoid wire harness.
11. Install a new O-ring (F) on a new shift solenoid wire harness (G), and install the shift solenoid wire harness in the transmission housing.
12. Connect the shift solenoid wire harness terminals to shift solenoid valves:
^ 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.
13. Install a new gasket, the dowel pins, and the shift solenoid valve cover.
14. Check the connector for rust, dirt, or oil, clean or repair as needed, then connect the connector securely.
15. Refill the transmission with ATF.
16. Install the splash shield.
17. Install the left front wheel.
