Solution

1. Preparation

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

2. Change Engine Oil and Filter

Sub-steps:
1. Drain the old oil by removing the oil drain plug under the engine.
2. Replace the oil filter using an oil filter wrench.
3. Install a new oil filter, ensuring it is tightened to the manufacturer's specifications.
4. Fill the engine with the correct type and amount of oil as specified in the owner's manual.
5. Reinstall the oil drain plug and torque it to the specified value (usually around 25 Nm).

3. Replace Oil Pressure Sending Unit (if faulty)

Sub-steps:
1. Locate the oil pressure sending unit (usually near the oil filter).
2. Disconnect the electrical connector from the sending unit.
3. Remove the sending unit using a suitable socket or wrench.
4. Install the new sending unit and tighten it to the recommended torque (typically around 20 Nm).
5. Reconnect the electrical connector.

4. Recheck Oil Pressure

Sub-steps:
1. Reconnect the battery.
2. Start the engine and let it idle.
3. Use a mechanical oil pressure gauge to check the oil pressure again.
4. Ensure the reading meets the manufacturer’s specifications (usually around 1.5-4.5 bar at idle).
