Solution

1. Preparation

Tools Required: OBD-II scanner, mechanical oil pressure gauge, socket set, torque wrench, oil filter wrench, rags.
Ensure the engine is cool and parked on a level surface.
Disconnect the battery before starting any work to prevent electrical shorts.

2. Check and Adjust Oil Level

Remove the dipstick and wipe it clean.
Reinsert the dipstick and remove it again to check the oil level.
If low, add the appropriate type and amount of oil (refer to owner's manual for specifications).

3. Replace Oil Pressure Sending Unit (if faulty)

Locate the oil pressure sending unit (usually near the oil filter).
Using a socket wrench, unscrew the old sending unit.
Apply thread sealant to the new sending unit and install it, tightening to the manufacturer's specified torque (usually around 10-15 ft-lbs).
Reconnect the electrical connector.

4. Change Oil and Filter

Place an oil pan under the oil pan.
Remove the drain plug using a socket wrench and allow the oil to drain completely.
Replace the oil filter using an oil filter wrench, ensuring that the rubber O-ring from the old filter is removed.
Reinstall the drain plug, tightening it to the manufacturer's specifications (typically 20-25 ft-lbs).
Fill the engine with new oil, using the recommended oil type and quantity.

5. Test Oil Pressure

Install a mechanical oil pressure gauge where the oil pressure sending unit was located.
Start the engine and monitor the gauge for proper pressure (typically 25-65 PSI at idle, depending on engine temperature).
If pressure is still low, further internal engine inspection may be required.
