Solution

1. Preparation

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

2. Check and Top Off Engine Oil

Remove the dipstick and wipe it clean.
Reinsert the dipstick fully and remove it again to check the oil level.
If low, add the appropriate type and amount of engine oil as specified in the owner’s manual.

3. Replace Oil Filter

Place a drain pan under the oil filter.
Use an oil filter wrench to remove the old oil filter.
Apply a thin layer of new oil to the rubber gasket of the new oil filter.
Install the new oil filter by hand, ensuring it is snug but not overtightened.

4. Test Oil Pressure

Remove the oil pressure sending unit using a socket wrench.
Install the oil pressure gauge in place of the sending unit.
Start the engine and monitor the oil pressure reading on the gauge. Compare it to the specifications in the service manual.
If oil pressure is low, proceed to check the oil pump.

5. Inspect Oil Pump (if necessary)

Drain the engine oil and remove the oil pan.
Inspect the oil pump for wear or damage.
Replace the oil pump if it is faulty, following the manufacturer’s specifications for installation.
