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. [1][2]Removal And Installation.
NG - GO TO 2.
2.CHECK OIL PRESSURE SENSOR POWER SUPPLY





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






OK or NG
OK - GO TO 3.
NG - Check oil pressure sensor power supply circuit for short to ground. If OK then replace double meter. [1][2]Removal And Installation.
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.






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.






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






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.






OK or NG
OK - Replace double meter (oil pressure gauge does not move).
OK - Replace oil pressure sensor (oil pressure gauge moves but reads incorrectly).
NG - Repair harness or connector between double meter and oil pressure sensor.
