Engine Coolant Temperature (ECT) Switch
ECT SWITCH INSPECTION
1. REMOVE ENGINE UNDER COVER
2. DRAIN ENGINE COOLANT
3. REMOVE ECT SWITCH
(a) Disconnect the ECT switch connector.
(b) Remove the ECT switch.
(c) Remove the O–ring from the ECT switch.
4. INSPECT ECT SWITCH
(a) Using an ohmmeter, check that there is no continuity between the terminals when the coolant temperature is above 97°C (207°F).
(b) Using an ohmmeter, check that there is continuity between the terminals when the coolant temperature is below 88°C (190°F).
If continuity is not as specified, replace the switch.
5. REINSTALL ECT SWITCH
(a) Install a new O–ring to the ECT switch.
(b) Apply soapy water to the O–ring.
(c) Install the ECT switch.
