DTC CONFIRMATION PROCEDURE

1.

PRECONDITIONING

If DTC Confirmation Procedure has been previously conducted, always perform the following before conduct-
ing the next test.
1.

Turn ignition switch OFF and wait at least 10 seconds.

2.

Turn ignition switch ON.

3.

Turn ignition switch OFF and wait at least 10 seconds.

>> GO TO 2.

2.

PERFORM DTC CONFIRMATION PROCEDURE

1.

Start engine and wait at least 5 seconds.

2.

Check 1st trip DTC.

Is 1st trip DTC detected?

YES

>> Proceed to 

EC-259, "Diagnosis Procedure"

.

NO

>> INSPECTION END

Diagnosis Procedure

INFOID:0000000009651103

1.

CHECK EOT SENSOR POWER SUPPLY

1.

Disconnect engine oil temperature (EOT) sensor harness connector.

2.

Turn ignition switch ON.

3.

Check the voltage between EOT sensor harness connector and ground.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Repair open circuit, short to ground or short to power in harness or connectors.

2.

CHECK EOT SENSOR GROUND CIRCUIT FOR OPEN AND SHORT

1.

Turn ignition switch OFF.

2.

Disconnect ECM harness connector.

3.

Check the continuity between EOT sensor harness connector and ECM harness connector.

4.

Also check harness for short to ground and short to power.

DTC No.

Trouble Diagnosis 

Name

DTC detecting condition

Possible Cause

P0197

Engine oil tempera-
ture sensor circuit low 
input

An excessively low voltage from the sensor is 
sent to ECM.

• Harness or connectors

(The sensor circuit is open or shorted.)

• Engine oil temperature sensor

P0198

Engine oil tempera-
ture sensor circuit 
high input

An excessively high voltage from the sensor is 
sent to ECM.

3.

CHECK ENGINE OIL TEMPERATURE SENSOR

Check engine oil temperature sensor. Refer to 

EC-260, "Component Inspection"

.

Is the inspection result normal?

YES

>> Check intermittent incident. Refer to 

GI-42, "Intermittent Incident"

.

NO

>> Replace engine oil temperature sensor. Refer to 

EM-66, "Exploded View"

.

Component Inspection

INFOID:0000000009651104

1.

CHECK ENGINE OIL TEMPERATURE SENSOR

1.

Turn ignition switch OFF.

2.

Disconnect engine oil temperature sensor harness connector.

3.

Remove engine oil temperature sensor. Refer to 

EM-66, "Exploded View"

.

4.

Check resistance between engine oil temperature sensor termi-
nals by heating with hot water as shown in the figure.

Is the inspection result normal?

YES

>> INSPECTION END

NO

>> Replace engine oil temperature sensor. Refer to
