DTC Description
DTC DETECTION LOGIC
| DTC No. | CONSULT screen terms (Trouble diagnosis content) | DTC detecting condition |
| P0197 | EOT SEN/CIRC (Engine oil temperature sensor low) | An excessively low voltage from the engine oil temperature sensor is sent to ECM. |
| P0198 | EOT SEN/CIRC (Engine oil temperature sensor high) | An excessively high voltage from the engine oil temperature sensor is sent to ECM. |
POSSIBLE CAUSE
- Harness or connectors (EOT sensor circuit is open or shorted.)
- Engine oil temperature sensor
FAIL-SAFE
Exhaust valve timing control does not function.
DTC CONFIRMATION PROCEDURE
1.PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always perform the following procedure before conducting the next test.
- Turn ignition switch OFF and wait at least 10 seconds.
- Turn ignition switch ON.
- Turn ignition switch OFF and wait at least 10 seconds.
>> GO TO 2.
2.PERFORM DTC CONFIRMATION PROCEDURE
- Start engine and wait at least 5 seconds.
- Check 1st trip DTC.
Is 1st trip DTC detected? YES >> Proceed to EC-281, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis Procedure
1.CHECK ENGINE OIL TEMPERATURE SENSOR POWER SUPPLY
- Turn ignition switch OFF.
- Disconnect engine oil temperature (EOT) sensor harness connector.
- Turn ignition switch ON.
- Check the voltage between EOT sensor harness connector and ground.
Is the inspection result normal? YES >> GO TO 3.
NO >> GO TO 2.
2.CHECK ENGINE OIL TEMPERATURE SENSOR POWER SUPPLY CIRCUIT
- Turn ignition switch OFF.
- Disconnect ECM harness connector.
- Check the continuity between EOT sensor harness connector and ECM harness connector.
- Also check harness for short to ground.
Is the inspection result normal? YES >> Perform the trouble diagnosis for power supply circuit.
NO >> Repair or replace error-detected parts.
3.CHECK EOT SENSOR GROUND CIRCUIT
- Turn ignition switch OFF.
- Disconnect ECM harness connector.
- Check the continuity between EOT sensor harness connector and ECM harness connector.
- Also check harness for short to power.
Is the inspection result normal? YES >> GO TO 4.
NO >> Repair or replace error-detected parts.
4.CHECK ENGINE OIL TEMPERATURE SENSOR
Check the engine oil temperature sensor. Refer to EC-279, "Component Inspection".
Is the inspection result normal? YES >> GO TO 5.
NO >> Replace engine oil temperature sensor. Refer to EC-14, "Component Parts Location".
5.CHECK INTERMITTENT INCIDENT
Refer to GI-41, "Intermittent Incident".
>> INSPECTION END
Component Inspection
1.CHECK ENGINE OIL TEMPERATURE SENSOR
- Turn ignition switch OFF.
- Disconnect engine oil temperature sensor harness connector.
- Remove engine oil temperature sensor.
- Check resistance between engine oil temperature sensor terminals 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 EC-14, "Component Parts Location".
