Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery before starting repairs to prevent electrical issues.

2. Check and Top Off Engine Oil

Sub-steps:
1. Remove the oil dipstick and wipe it clean.
2. Reinsert the dipstick and remove it again to check the oil level.
3. If low, add the appropriate engine oil (refer to the owner's manual for the correct oil type).
Tools Required:
- Funnel

3. Replace Oil Filter and Engine Oil

Sub-steps:
1. Place an oil catch pan under the oil pan.
2. Remove the oil drain plug and allow old oil to drain completely.
3. Replace the oil filter using an oil filter wrench.
4. Install the drain plug with a torque value per the manufacturer’s specification.
5. Add new engine oil through the oil filler cap using the correct type and amount as per the owner's manual.
Tools Required:
- Oil catch pan
- Socket set
- Oil filter wrench

4. Inspect and Replace Oil Pressure Sending Unit (if necessary)

Sub-steps:
1. Locate the oil pressure sending unit (usually near the oil filter).
2. Disconnect the wiring harness from the sending unit.
3. Remove the sending unit using a socket.
4. Install the new sending unit and reconnect the harness.
Tools Required:
- Socket set

5. Test Oil Pressure

Sub-steps:
1. Install a mechanical oil pressure gauge by removing the oil pressure sending unit.
2. Start the engine and observe the pressure reading.
3. If the pressure is low, further inspection might be needed for oil pump or internal engine issues.
Tools Required:
- Mechanical oil pressure gauge
