Electric Oil Pressure Gauge

Testing electric oil pressure gauge

Oil Pressure Gauge Sensor (B5):

- Turn key in steering lock to position 2 (battery voltage).
- Unplug electrical connection from oil pressure gauge sensor (B5).
Specified reading: 3 bar.

- If specified reading is not achieved: test cable from oil pressure gauge sensor (B5) to instrument for short to ground.
- Cable in order: replace instrument.
- With engine off, oil pressure gauge rises. Connect cable from oil pressure gauge sensor (B5) to ground. If reading is 0 bar, replace oil pressure gauge sensor (B5).
- If reading remains at 3 bar cable has open circuit.

Note: The oil pressure gauge is controlled electrically. The oil pressure gauge sensor (B5) installed in the oil filter attachment controls the gauge in the instrument cluster. There will be a positive reading at the oil pressure gauge in the instrument cluster when the ignition is switched on. Negative is applied to the oil pressure gauge through the sensor (B5). As the pressure rises, the ohmic resistance of the oil pressure gauge sensor (B5) increases and the reading of the gauge alters.

Oil Pressure Test Data:

Note: The resistance of the oil pressure gauge sensor (B5) depends on the pressure in the system.
