Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Disconnect the battery to ensure safety.

2. Check and Top Off Oil Level

Remove the oil fill cap.
Use a funnel to add the appropriate type of oil (5W-20 or as specified in the owner's manual) to reach the proper level.
Replace the oil fill cap securely.

3. Replace Oil Pressure Sending Unit

Locate the oil pressure sending unit near the oil filter.
Disconnect the electrical connector from the unit.
Use a socket wrench to remove the sending unit.
Install the new oil pressure sending unit and torque it to the manufacturer's specification (typically around 15-20 ft-lbs).
Reconnect the electrical connector.

4. Inspect and Replace Oil Pump (if necessary)

Drain the engine oil completely.
Remove the oil pan by unbolting it from the engine block (use a torque wrench for reinstallation).
Take out the oil pump by removing the mounting bolts.
Inspect the oil pump for signs of wear or damage; replace if necessary.
Install the new oil pump and torque the bolts to the manufacturer's specifications.
Reinstall the oil pan and refill with new oil.

5. Final Checks

Reconnect the battery.
Start the engine and monitor the oil pressure gauge.
Check for leaks around the oil filter, sending unit, and oil pan.
