Solution

1. Preparation

Gather tools: OBD-II scanner, oil pressure gauge, socket set, wrench set, oil filter wrench, and torque wrench.
Ensure the engine is cool and parked on a level surface.
Disconnect the battery to prevent electrical issues.

2. Change Engine Oil and Filter

Drain Old Oil:
- Place a drain pan under the oil pan.
- Remove the oil drain plug using a socket wrench (Torque: 20 ft-lbs).
- Allow oil to completely drain into the pan.
Replace Oil Filter:
- Use an oil filter wrench to remove the old oil filter.
- Apply a thin layer of new oil on the rubber gasket of the new filter.
- Install the new filter hand-tight.
Refill Engine Oil:
- Reinstall the oil drain plug (Torque: 20 ft-lbs).
- Fill the engine with the recommended oil type (5W-30 or as specified in the owner’s manual) through the oil filler cap.
- Start the engine and let it run for a few minutes, then recheck the oil level with a dipstick and add more oil if necessary.

3. Replace Oil Pressure Sending Unit (if faulty)

Locate the Sending Unit:
- Identify the oil pressure sending unit on the engine block (usually near the oil filter).
Remove Old Sending Unit:
- Disconnect the electrical connector.
- Use a socket or wrench to unscrew the sending unit.
Install New Sending Unit:
- Apply thread sealant to the threads of the new sending unit.
- Screw it into place and tighten securely (Torque: 15 ft-lbs).
- Reconnect the electrical connector.
