2. Warm up the engine by driving some distance. Once the coolant has warmed up to operating temperature, drive another 5 km or so to ensure sufficient oil temperature of approximately +80°C.
3. Disconnect the power wire from the oil pressure sensor and unscrew the sensor (see illustration). The illustration shows a 1.4-/1.6-liter petrol engine (E7J/K7M). On other engines, the oil pressure sensor is located on the left side of the oil filter or next to the oil filter.

4. Connect the appropriate pressure gauge instead of the oil pressure sensor.
5. Start the engine and let it run at the speed corresponding to the test mode. Read the pressure gauge reading.
1.4-/1.6-litre petrol engine (E7J/K7M)
Minimum oil pressure: at idle - 1.0 bar; at 3000 rpm - 3.0 bar.
2.0 litre petrol engine, 1.9 litre diesel engine
Minimum oil pressure: at idle - 1.2 bar; at 3000 rpm - 3.5 bar.
6. Screw the oil pressure sensor back into place, replacing the old sealing ring with a new one. The tightening torque of the sensor is 35 Nm.
