Solution

1. Preparation

Tools Required: OBD-II scanner, mechanical oil pressure gauge, socket set, torque wrench, oil filter wrench, oil catch pan.
Ensure the vehicle is parked on a level surface and the engine is cool before starting.

2. Check and Top Off Engine Oil

Remove the oil filler cap and inspect the oil level using the dipstick.
If the oil level is low, top off with the manufacturer-recommended oil type (e.g., 5W-30 synthetic).
Replace the oil filler cap securely.

3. Inspect and Replace Oil Filter

Tools Required: Oil filter wrench.
Place an oil catch pan under the oil filter.
Use the oil filter wrench to remove the old oil filter.
Apply a thin layer of oil to the rubber O-ring of the new oil filter and install it.
Tighten the filter according to manufacturer specifications (usually hand-tight plus a quarter turn).

4. Test Oil Pressure

Remove the oil pressure sending unit from the engine block.
Install the mechanical oil pressure gauge in its place.
Start the engine and check the oil pressure reading on the gauge. It should be within the specified range (consult the service manual for exact values).
If the pressure is low, proceed to the next step.

5. Inspect and Replace Oil Pump (if necessary)

Disconnect the battery to ensure safety.
Drain the engine oil completely.
Remove the oil pan by unscrewing the bolts and carefully detaching it.
Remove the old oil pump and replace it with a new one, ensuring it is properly aligned.
Reinstall the oil pan, ensuring a new gasket is used and all bolts are torqued to specification.
Refill the engine with the appropriate oil type.
