Solution

1. Preparation

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

2. Check and Top Off Engine Oil

Open the hood and locate the dipstick.
Remove the dipstick, wipe it clean, and reinsert it fully.
Pull the dipstick out again to check the oil level.
If the oil level is low, add the appropriate type of engine oil as specified in the owner’s manual.
Recheck the oil level after adding oil.

3. Replace Oil Filter (if necessary)

Place an oil catch pan under the oil filter.
Use the 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 by hand until snug, then tighten it slightly with the wrench.
Refill the engine with the correct amount and type of oil.

4. Test Oil Pressure

Remove the oil pressure sending unit using the appropriate socket.
Install the mechanical oil pressure gauge in place of the sending unit.
Start the engine and observe the pressure reading on the gauge.
The pressure should be within the specifications found in the owner’s manual (typically 20-60 PSI at idle and higher at RPM).

5. Inspect and Replace Oil Pump (if needed)

If the oil pressure is low and the oil is at the correct level, inspect the oil pump.
Remove any necessary components for access (intake manifold, timing cover if applicable).
Remove the oil pump and inspect for damage or wear.
Install a new oil pump if necessary, following the manufacturer's torque specifications for any bolts.
