Solution

1. Preparation

Gather tools and materials.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical issues.

2. Check and Top Off Engine Oil

Remove the dipstick and wipe it clean.
Reinsert the dipstick and remove it again to check the oil level.
If low, add the recommended oil type (e.g., 5W-30) until it reaches the proper level.

3. Replace Oil Pressure Sending Unit

Locate the oil pressure sending unit, typically near the oil filter.
Disconnect the electrical connector and remove the unit using a socket wrench.
Install the new sending unit, ensuring it is tightened to manufacturer specifications (typically around 20 Nm).
Reconnect the electrical connector.

4. Conduct Oil Pressure Test

Remove the oil pressure sending unit and install a mechanical oil pressure gauge.
Start the engine and observe the pressure reading.
If the reading is below the manufacturer's specifications (usually around 1.5 to 5 bar), further investigation is necessary.

5. Oil and Filter Change

Drain the engine oil using a wrench to remove the oil drain plug.
Replace the oil filter with a new one, ensuring the rubber gasket is lubricated.
Reinstall the drain plug and refill the engine with the specified oil type.
