Oil Pressure Gauge Circuit Test
- Remove oil pressure gauge from instrument cluster. Check for continuity in the wire between oil pressure sender and oil pressure sender input pin. See Figure . Repair wiring if continuity does not exist.
- With ignition on, check for battery voltage across oil pressure gauge (B+) pin and oil pressure gauge ground pin. See Figure . If no voltage exists, check wiring for damage and power supply for oil pressure gauge (B+) pin.
