Transmission Temperature Sensor/Switch: Testing and Inspection
ATF Temperature Sensor Test/Replacement1. Lift the vehicle up on a hoist, 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 splash shield.
3. Disconnect the shift solenoid harness connector.
4. Measure the ATF temperature sensor resistance between shift solenoid harness connector terminals No. 6 and No. 7.
Standard: 50 Ohms - 25 k Ohms
5. If the resistance is out of standard, replace the ATF temperature sensor and the solenoid harness; go to step 6. The ATF temperature sensor is not available separately from the solenoid harness.
If the measurement is within the standard, connect the connector securely, and install the splash shield.
6. Remove the drain plug (A), and drain the automatic transmission fluid (ATF).
7. Reinstall the drain plug with a new sealing washer (B).
8. Remove the shift solenoid valve cover (A), the dowel pins (B), and the gasket (C).
9. Remove the shift solenoid harness connector (E), and replace it.
10. Install the new O-ring (F) on the new shift solenoid harness connector, and install the connector in the transmission housing.
11. Connect the connector with the WHT and ORN wires to shift solenoid valve B. The ATF temperature sensor is assembled in the connector with the WHT wires.
12. Connect the BLU wire terminal to shift solenoid valve A, the GRN wire terminal to shift solenoid valve C, and the YEL wire terminal to shift solenoid valve D.
13. Install the shift solenoid valve cover, the dowel pins, and a new gasket.
14. Check the connector for rust, dirt, or oil, then connect the connector securely.
15. Refill the transmission with ATF.
16. Install the splash shield.
