Coolant Temperature Sensor/Switch (For Computer): Testing and Inspection

ENGINE COOLANT TEMPERATURE SENSOR INSPECTION
1. Drain engine coolant.
2. Remove RH engine service hole cover.

(See step 1 in valve clearance inspection and adjustment in Engine Mechanical)

3. Remove engine coolant temperature sensor connector.
- Disconnect the engine coolant temperature sensor.
- Remove the engine coolant temperature sensor and gasket.

4. Inspect engine coolant temperature sensor.





- Using an ohmmeter, measure the resistance between the terminals.

Resistance: Refer to the graph





- If the resistance is not as specified, replace the engine coolant temperature sensor.

5. Reinstall engine coolant temperature sensor.
- Install a new gasket to the engine coolant temperature sensor.
- Install the engine coolant temperature sensor.

Torque: 25 N.m (17.5 ft.lb.)

- Connect the engine coolant temperature sensor connector.

6. Reinstall RH engine service hole cover.
7. Refill with engine coolant.
