ENGINE COOLANT TEMPERATURE (ECT) SENSOR

INSPECTION

1. DRAIN ENGINE COOLANT

2. REMOVE ECT SENSOR




a. Disconnect the ECT sensor connector.
b. Using SST, remove the ECT sensor and gasket.

3. INSPECT ECT SENSOR




Using an ohmmeter, measure the resistance between the terminals.

Resistance: Refer to the graph

If the resistance is not as specified, replace the ECT sensor.

4. REINSTALL ECT SENSOR
a. Install a new gasket to the ECT sensor.
b. Using SST; install the ECT sensor.
SST 09205-76030

Torque: 19.6 N.m (200 kgf.cm, 14 ft.lbf)

c. Connect the ECT sensor connector.

5. REFILL WITH ENGINE COOLANT
