Oil Pressure: Inspecting and Replacing the Oil Pressure Sensor





Oil Pressure: Inspecting And Replacing The Oil Pressure Sensor

Special Tools: 999 5270, 5271, 5272, 5273

NOTE: When checking the oil pressure, the engine should be at a temperature which corresponds to 15 minutes normal driving (100 degree C). Replace the oil and filter if the engine oil grade, type or condition cannot be determined.

Checking the engine oil pressure sensor







- Raise the car.
- Remove the engine cover.

Check:
- The oil pressure sensor cable and connectors
- Check for an open-circuit in the cable between the oil pressure sensor and the indicator lamp.
- Type and remedy; try a new pressure sensor.

NOTE: Use a new seal between the oil pressure sensor and the cylinder block.

Checking oil pressure







- Use oil pressure gauge kit 999 5270.
- Adapter 999 5273, hose 999 5272 and gauge 999 5271. Connect these items to the hole on the cylinder block for the oil pressure sensor.
- Start the engine. Read off the oil pressure at different engine speeds (RPM).

Minimum oil pressure at:
13.3 r/s (800 r/min) 0.10 MPa
14.2 r/s (850 r/min) 0.10 MPa
66.7 r/s (4000 r/min) minimum 0.35 MPa
66.7 r/s (4000 r/min) maximum 0.70 MPa

NOTE: The relief valve begins to open at 0.5 MPa.

Remove the tools.

Use a new gasket when installing the oil pressure sensor.

Tighten to 25 Nm.
