  - Tools Required: Socket set, oil catch pan
2. Replace the oil filter using an oil filter wrench.
  - Tools Required: Oil filter wrench
3. Install a new oil filter, ensuring the rubber O-ring is lubricated with new oil before installation.
4. Reinstall the oil drain plug and torque it to the manufacturer’s specifications (typically around 20-25 ft-lbs).
5. Refill the engine with the correct type and amount of new oil (5W-20 recommended for this model).

3. Inspect and Replace Oil Pump (if needed)

Sub-steps:
1. Disconnect the battery to prevent any electrical issues.
2. Remove the oil pan by unbolting it from the engine block.
3. Take out the old oil pump and inspect it for wear or damage.
4. Install the new oil pump, ensuring proper alignment and torque specifications are followed.
  - Tools Required: Torque wrench, socket set
5. Reinstall the oil pan and ensure a proper seal with a new gasket.

4. Check and Repair Oil Pressure Sending Unit

Sub-steps:
1. Locate the oil pressure sending unit and inspect for leaks or damage.
2. If faulty, remove and replace the sending unit.
  - Tools Required: Wrench set
3. Reconnect any wiring harnesses and ensure secure connections.
