ATF Temperature Sensor Test/Replacement
- 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.
- Remove the splash shield.
- Disconnect the shift solenoid harness connector.
- Measure the ATF temperature sensor resistance between shift solenoid harness connector terminals No. 6 and No. 7.
Standard: 50 Ξ©-25 kΞ©Β
- If the resistance is out of standard, replace the ATF temperature sensor and the solenoid harness; go to step Β 6. The ATF temperature sensor is not available separately from the shift solenoid harness.
If the resistance is within the standard, connect the connector securely, and install the splash shield.
- Remove the drain plug (A), and drain the automatic transmission fluid (ATF).
- Reinstall the drain plug with a new sealing washer (B).
- Remove the shift solenoid valve cover (A), dowel pins (B), and gasket (C).
- Disconnect the connectors, remove the shift solenoid harness connector (E), and replace it.
- Install the new O-ring (F) on the new shift solenoid harness connector, and install the connector in the transmission housing.
- Connect the WHT and ORN wires connector to shift solenoid valve B. The ATF temperature sensor is assembled in the WHT wires connector.
- Connect the harness terminals to the solenoids:
- BLU wire connector to shift solenoid valve A.
- GRN wire connector to shift solenoid valve C.
- YEL wire connector to shift solenoid valve D.
- Install the shift solenoid valve cover, dowel pins, and a new gasket.
- Check the connector for rust, dirt, or oil, then connect it securely.
