Solution

1. Preparation

Gather tools and materials: OBD-II scanner, mechanical oil pressure gauge, socket set, torque wrench, oil filter wrench, new oil filter, and engine oil.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Check and Top Up Engine Oil

Remove the dipstick, wipe it clean, and reinsert it to check the oil level.
If the oil level is low, add the appropriate type and amount of engine oil as specified in the owner's manual.
Check for any signs of contamination (milky appearance) in the oil.

3. Inspect and Replace Oil Filter

Use an oil filter wrench to remove the old oil filter.
Apply a small amount of new oil to the rubber gasket of the new oil filter.
Install the new oil filter and tighten it according to the manufacturer's specifications.

4. Test Oil Pressure

Remove the oil pressure sender unit and install the mechanical oil pressure gauge.
Start the engine and observe the oil pressure reading; it should fall within the manufacturer's specified range.
If the pressure is low, proceed to inspect the oil pump.

5. Inspect Oil Pump

If necessary, remove the oil pump for inspection. This may require draining the oil and removing the oil pan.
Check for signs of wear or damage on the pump and replace if necessary.

6. Reassemble and Test

Reinstall all components in the reverse order of removal.
Ensure all bolts and screws are tightened to the manufacturer's torque specifications.
Refill the engine with the appropriate amount of fresh oil.
