Solution

1. Preparation

Tools Required: OBD-II scanner, dipstick, mechanical oil pressure gauge, socket set, rags.
Safety Warnings: Ensure the engine is cool before starting any work. Disconnect the battery to prevent electrical shorts.

2. Change Engine Oil and Filter

Drain Oil:
- Place an oil catch pan under the oil pan.
- Remove the oil drain plug and let the oil drain completely.
Replace Oil Filter:
- Use an oil filter wrench to remove the old oil filter.
- Lubricate the rubber O-ring of the new filter with fresh oil and install it.
Refill Engine Oil:
- Replace the drain plug and tighten to the manufacturer’s torque specification (usually around 20-25 Nm).
- Pour the recommended engine oil into the engine (refer to the owner's manual for the correct oil type and capacity).

3. Replace Oil Pressure Sending Unit (if faulty)

Locate Sending Unit:
- Identify the oil pressure sending unit, usually near the oil filter or on the engine block.
Remove Old Unit:
- Disconnect the electrical connector and unscrew the sending unit using a socket.
Install New Unit:
- Apply thread sealant to the new unit’s threads and install it by hand, then tighten with a socket.
Reconnect Connector:
- Ensure the electrical connector is securely attached.

4. Check for Leaks

Start the engine and allow it to idle. Check for leaks around the oil filter, drain plug, and oil pressure sending unit.
