ENGINE COOLANT TEMPERATURE (ECT) SENSOR INSPECTION

1. Drain engine coolant.
2. Disconnect upper radiator hose from water outlet.
3. Remove No.2 timing belt cover.





4. Remove fuel pipe.
5. Remove ECT sensor.
(a) Disconnect the ECT sensor connector.





(b) Using SST remove the ECT sensor and gasket. SST 09205-76030

Ohmmeter Connection:

Reference Graph:

6. 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.
7. Reinstall ECT sensor.
(a) Install a new gasket to the ECT sensor.
(b) Using SST, install the ECT sensor. SST 09205-76030

Torque: 20 N.m (200 kgf.cm, 14 ft.lbf)

(c) Connect the ECT sensor connector.
8. Reinstall fuel pipe.
Install the fuel pipe with 4 new gaskets and the 2 union bolts.

Torque: 34.3 N.m (350 kgf.cm, 25 ft.lbf)

9. Reinstall No.2 timing belt cover.
10. Reconnect upper radiator hose to water outlet.
11. Refill with engine coolant.
