Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, manual oil pressure gauge, oil filter wrench, torque wrench, clean rags.
Ensure the vehicle is on a level surface and the engine is cool.
Disconnect the battery to avoid electrical shorts.

2. Check and Add Engine Oil

Remove the oil filler cap.
Use the dipstick to check the oil level; if low, add the manufacturer-recommended engine oil.
Replace the oil filler cap securely.

3. Replace Oil Filter

Locate the oil filter; use an oil filter wrench to remove it.
Apply a thin layer of new oil to the rubber gasket of the new oil filter.
Install the new oil filter by hand, then tighten according to specifications (typically 3/4 turn after the gasket makes contact).
Torque Value: Follow manufacturer specifications, usually around 18-25 ft-lbs.

4. Inspect and Replace Oil Pump (if necessary)

Remove the engine oil pan by unbolting all retaining bolts and gently prying it off.
Locate the oil pump; remove any attached components.
Replace the oil pump with a new unit if it shows signs of failure.
Reinstall the oil pan with a new gasket and torque to manufacturer specifications.

5. Verify Oil Pressure

Reconnect the battery.
Start the engine and allow it to idle.
Connect a manual oil pressure gauge to the oil pressure sending unit location.
Check if the oil pressure readings are within manufacturer specifications (usually around 25-65 psi at idle).
