Description
The engine coolant temperature sensor is used to detect the engine coolant temperature. The sensor modifies a voltage signal from the ECM. The modified signal returns to the ECM as the engine coolant temperature input. The sensor uses a thermistor which is sensitive to the change in temperature. The electrical resistance of the thermistor decreases as temperature increases.
<Reference data>
*: These data are reference values and are measured between ECM terminals 46 (Engine coolant temperature sensor) and 52 (Sensor ground).

DTC CONFIRMATION PROCEDURE
1.PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always perform the following before conducting the next test.
2.CHECK ENGINE COOLANT TEMPERATURE SENSOR FUNCTION
With CONSULT
With GST
Follow the procedure "With CONSULT" above.
3.PERFORM DTC CONFIRMATION PROCEDURE
With CONSULT
If "COOLAN TEMP/S" increases to more than 10C (50F) within 65 minutes, stop engine because the test result will be OK. CAUTION: Never overheat engine.
With GST
Follow the procedure "With CONSULT" above.
Diagnosis Procedure
1.CHECK GROUND CONNECTION
2.CHECK ENGINE COOLANT TEMPERATURE SENSOR
3.CHECK THERMOSTAT OPERATION
When the engine is cold [lower than 70C (158F)] condition, grasp lower radiator hose and confirm that the engine coolant does not flow.
4.CHECK INTERMITTENT INCIDENT
Component Inspection
