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 to avoid electrical shorts.

2. Check Oil Level and Quality

Sub-steps:
- Remove the dipstick and wipe it clean.
- Reinsert the dipstick and remove it again to check the oil level.
- If low, add the recommended oil type (typically 0W-20 for this model).
- Visually inspect the oil; if it appears dark and gritty, a change is needed.

3. Change Engine Oil and Filter

Sub-steps:
- Place an oil drain pan under the oil pan.
- Remove the oil drain plug and let the old oil drain completely.
- Replace the oil filter using an oil filter wrench, ensuring the rubber O-ring is removed.
- Install a new oil filter by hand-tightening it.
- Reinstall the drain plug with a torque of 25 ft-lbs.
- Fill the engine with new oil through the oil filler cap, using the correct amount (typically 4.4 quarts).

4. Replace Oil Pressure Sending Unit (if necessary)

Sub-steps:
- Locate the oil pressure sending unit, usually near the oil filter.
- Disconnect the electrical connector from the sending unit.
- Use a socket to remove the sending unit.
- Install the new sending unit and tighten to manufacturer specifications.
- Reconnect the electrical connector.

5. Test Oil Pressure

Sub-steps:
- Remove the oil pressure sending unit.
- Install an oil pressure gauge in its place.
- Start the engine and monitor the oil pressure reading.
- If the pressure is low, further inspection of the oil pump or engine internals may be required.
