Solution

1. Preparation

Gather tools and ensure the vehicle is parked on a level surface.
Disconnect the battery to prevent any electrical issues.
Allow the engine to cool before starting work.

Tools Required:

OBD-II scanner
Mechanical oil pressure gauge
Socket set
Torque wrench
Oil filter wrench
Oil catch pan

2. Check and Top Off Engine Oil

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

3. Inspect and Replace Oil Filter

Use an oil filter wrench to remove the old oil filter.
Clean the mounting surface on the engine where the filter attaches.
Install a new oil filter, ensuring the rubber O-ring is lubricated and properly seated.
Tighten the filter to the manufacturer's specifications.

4. Replace Engine Oil

Drain the old engine oil using the oil catch pan by removing the oil drain plug.
Allow the oil to fully drain, then replace and torque the drain plug to the manufacturer's specifications.
Refill with new engine oil through the oil filler cap, using the recommended oil type and quantity.

5. Test Oil Pressure

Connect a mechanical oil pressure gauge to the oil pressure sending unit location.
Start the engine and observe the oil pressure reading on the gauge.
If the pressure is below specifications, further inspection of the oil pump and related components is necessary.
