Note! When checking the oil pressure, the engine should be at a temperature which corresponds to 15 minutes normal driving (100°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 OIL PRESSURE METER 999 5270 Oil Pressure Meter.
Adapter 999 5273 NIPPLE 999 5273 Nipple , hose 999 5272 Adapter included in 9995270 999 5272 Adapter Included In 9995270 and gauge 999 5271 Pressure gauge incl in 9995270 999 5271 Pressure gauge incl in 9995270. 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).






Note! The relief valve begins to open at 0.5 MPa.

Remove the tools.
Use a new gasket when installing the oil pressure sensor.
