Solution

1. Preparation

Tools Required:
- OBD-II scanner
- Mechanical oil pressure gauge
- Socket set
- Oil filter wrench
- Torque wrench
- Pliers
- Rags for cleanup
Safety Warnings:
- Allow the engine to cool before performing any work.
- Always wear gloves and safety glasses.

2. Check and Top Off Engine Oil

Sub-steps:
1. Open the hood and locate the engine oil dipstick.
2. Remove the dipstick, clean it with a rag, reinsert it, and remove it again to check the oil level.
3. If the oil level is low, add the appropriate type and viscosity of oil as specified in the owner’s manual.
4. Recheck the oil level to ensure it is within the recommended range.

3. Replace Oil Filter

Sub-steps:
1. Use an oil filter wrench to remove the old oil filter.
2. Prepare the new oil filter by applying a thin layer of clean oil to the rubber gasket.
3. Install the new oil filter by hand, tightening it according to the manufacturer's specifications (usually hand-tight plus a quarter turn).
4. Ensure there are no oil leaks around the new filter.

4. Test Oil Pressure

Sub-steps:
1. Locate the oil pressure sending unit and disconnect the electrical connector.
2. Remove the sending unit using the appropriate socket.
3. Install the mechanical oil pressure gauge in place of the sending unit.
4. Start the engine and observe the oil pressure reading.
5. If the pressure is below specifications, further investigation into the oil pump or internal engine components may be necessary.

5. Replace Oil Pressure Sending Unit (if necessary)

Sub-steps:
1. If the sending unit is faulty, replace it with a new unit.
2. Reconnect the electrical connector securely.
3. Check for leaks after starting the engine.
