CHECK OIL PRESSURE SENSOR POWER SUPPLY CIRCUIT
1. Disconnect triple meter and oil pressure switch connector.
2. Check harness continuity (open circuit) between triple meter harness connector M44 terminal 9 (R/L) and oil pressure sensor harness connector F21 terminal 1 (R/L).
  Continuity should exist.
3. Check harness continuity (short circuit) between triple meter harness connector M44 terminal 9 (R/L) and ground.
  Continuity should not exist.
OK or NG

OK: GO TO 4.

NG: Repair harness or connector between triple meter and oil pressure sensor.

CHECK OIL PRESSURE SENSOR SIGNAL CIRCUIT
1. Check harness continuity (open circuit) between triple meter harness connector M44 terminal 8 (LG/R) and oil pressure sensor harness connector F21 terminal 2 (G).
  Continuity should exist.
2. Check harness continuity (short circuit) between triple meter harness connector M44 terminal 8 (LG/R) and ground.
  Continuity should not exist.
OK or NG

OK: GO TO 5.

NG: Repair harness or connector between triple meter and oil pressure sensor.
