Warm up the engine while driving, the oil temperature should not be below 80°C.
Disconnect the wire from the oil pressure sensor and unscrew the sensor.
Insert a pressure gauge in place of the sensor.
With the engine idling, read the oil pressure on the pressure gauge
After applying sealant to 2-3 threads, insert and secure the oil pressure sensor.
The oil pressure sensor is mounted in front of the engine. When the engine is running and the oil pressure is above approximately 0.7 bar, the sensor is triggered and disconnects the electrical circuit of the control lamp, the lamp does not light. When the oil pressure is below 0.7 bar, the sensor returns to its initial position and connects the electrical circuit of the control lamp. The lamp lights up.
You can check the sensor readings in the set mode in the following order:
- Turn off the engine and remove the wire from the oil pressure sensor.
- Connect an ohmmeter between the oil pressure sensor contact and the engine block. The resistance should be 0 ohms.
- When the engine is idling, the instrument should show infinity.
- If one of the two measurements does not correspond to the required value, the oil pressure sensor must be replaced. If both measurements are correct, check the electrical wire going to the test light.
Connect the wire to the oil pressure sensor.
Checking the removed oil pressure sensor is as follows:
Connect an ohmmeter between the contact and the oil pressure sensor body. The resistance should be 0 Ohm.
Insert a thin needle into the oil hole of the switch and press lightly. The device should show infinity.
If at least one of the two measurements is not performed, the sensor must be replaced.
Use an air pump to create a pressure of 0.5 bar in the oil hole of the sensor. The resistance should be 0 Ohm. During this procedure, you need to ensure that air is released.
