Oil Pressure Sensor Inspection

1. CHECK OIL PRESSURE SENSOR SIGNAL





1. Turn ignition switch ON.
2. Check voltage between double meter harness connector M89 terminal 4 and ground.





OK or NG
OK >> Replace double meter. Refer to Double Meters.
NG >> GO TO 2.
2. CHECK OIL PRESSURE SENSOR POWER SUPPLY





Check voltage between double meter harness connector M89 terminal 3 and ground.

Approx. 5.5 V

OK or NG
OK >> GO TO 3.
NG >> Replace double meter. Refer to Double Meters.
3. CHECK OIL PRESSURE SENSOR POWER SUPPLY CIRCUIT





1. Turn ignition switch OFF.
2. Disconnect double meter and oil pressure sensor connectors.
3. Check continuity between double meter harness connector M89 (A) terminal 3 and oil pressure sensor harness connector F32 (B) terminal 3.

Continuity should exist.

4. Check continuity between double meter harness connector M89 (A) terminal 3 and ground.

Continuity should not exist.

OK or NG
OK >> GO TO 4.
NG >> Repair harness or connector between double meter and oil pressure sensor.
4. CHECK OIL PRESSURE SENSOR SIGNAL CIRCUIT





1. Check continuity between double meter harness connector M89 (B) terminal 4 and oil pressure sensor harness connector F32 (A) terminal 2.

Continuity should exist.

2. Check continuity between double meter harness connector M89 (B) terminal 4 and ground.

Continuity should not exist.

OK or NG
OK >> GO TO 5.
NG >> Repair harness or connector between double meter and oil pressure sensor.
5. CHECK OIL PRESSURE SENSOR GROUND CIRCUIT





Check continuity between double meter harness connector M89 (A) terminal 5 and oil pressure sensor harness connector F32 (B) terminal 1.

Continuity should exist.

OK or NG
OK >> Replace oil pressure sensor.
NG >> Repair harness or connector between double meter and oil pressure sensor.
