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.INSPECTION START
2.PERFORM COMPONENT FUNCTION CHECK
Perform component function check. Refer to EC-202, "Component Function Check".
NOTE: Use the component function check to check the overall function of the ECT sensor circuit. During this check, a 1st trip DTC might not be confirmed.
3.PRECONDITIONING
If DTC CONFIRMATION PROCEDURE has been previously conducted, always perform the following procedure before conducting the next test.
TESTING CONDITION:
4.PERFORM DTC CONFIRMATION PROCEDURE
NOTE: The vehicle must be cooled with the food open.
