Allow the engine to cool down if it has been running.

2. Check and Add Engine Oil

Sub-steps:
- Remove the dipstick, clean it, and reinsert it to check the oil level.
- If the oil level is low, add the recommended oil type (SAE 0W-20 or as specified in the owner’s manual) through the oil filler cap.
Tools Required: Oil container, funnel.

3. Replace Oil Filter

Sub-steps:
- Use an oil filter wrench to remove the old oil filter.

- Replace the drain plug with a new washer, torque to manufacturer's specifications (typically around 30 ft-lbs).
- Fill the engine with the appropriate amount of new oil through the oil filler cap.
Tools Required: Socket set, oil drain pan, funnel.

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

Sub-steps:
- Locate the oil pressure sending unit (usually near the oil filter).
- Disconnect the electrical connector and remove the sending unit using a socket wrench.
- Install the new sending unit, torque to specifications.
- Reconnect the electrical connector.
Tools Required: Socket set.

6. Test Oil Pump Functionality (if oil pressure is still low)

Sub-steps:
- Remove the oil pump from the engine following the service manual procedures.
- Inspect for wear and damage, replace if necessary.
- Reinstall the oil pump, ensuring all connections are secure.
Tools Required: Socket set, torque wrench.
