Transmission Temperature Sensor/Switch: Testing and Inspection
ATF Temperature Sensor Test/Replacement
1. 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 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 kohms
5. If the resistance is out of standard, go to step 6, and replace the ATF temperature sensor and solenoid harness. The ATF temperature sensor is not
available separately from the shift solenoid harness.

If the resistance is within the standard, the test is complete, 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), the gasket (C), and the harness clamp bracket (D).
