Description
The engine oil temperature sensor is used to detect the engine oil temperature. The sensor modifies a voltage signal from the ECM.
The modified signal returns to the ECM as the engine oil 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 54 (Engine oil temperature sensor) and 52 (Sensor ground).

NOTE: If DTC P0196 is displayed with DTC P0197 or P0198, first perform the trouble diagnosis for DTC P0197 or P0198.
DTC CONFIRMATION PROCEDURE
1.INSPECTION START
2.PRECONDITIONING
If DTC CONFIRMATION PROCEDURE has been previously conducted, always perform the following procedure before conducting the next test.
TESTING CONDITION: Before performing the following procedure, confirm that battery voltage is 11 V or more at idle.
3.PERFORM DTC CONFIRMATION PROCEDURE FOR MULFUNCTION A-I
4.PERFORM DTC CONFIRMATION PROCEDURE FOR MULFUNCTION A-II
With CONSULT
If it is above 80C (176F), go to the following steps.
If it is below 80C (176F), warm engine up until "COOLAN TEMP/S" indicates more than 80C (176F).
Then perform the following steps.
NOTE: Do not turn ignition switch OFF until step 8.
If they are within the specified range, perform the following steps.
If they are out of the specified range, soak the vehicle to meet the above conditions. Then perform the following steps.
NOTE:
With GST
Follow the procedure "With CONSULT" above.
5.PERFORM COMPONENT FUNCTION CHECK (FOR MULFUNCTION B)
Perform component function check.
NOTE: Use the component function check to check the overall function of the EOT sensor circuit. During this check, a 1st trip DTC might not be confirmed.
6.PRECONDITIONING
If DTC CONFIRMATION PROCEDURE has been previously conducted, always perform the following procedure before conducting the next test.
TESTING CONDITION:
