Solution

1. Preparation

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

2. Check and Fill Engine Oil

Sub-step 1: Remove the oil filler cap and check the oil level using the dipstick.
Sub-step 2: If the oil is low, add the appropriate type and grade of engine oil as specified in the owner's manual.
Sub-step 3: Recheck the oil level after adding oil and replace the oil filler cap securely.

3. Replace Oil Filter (If Necessary)

Sub-step 1: Use the oil filter wrench to remove the old oil filter. Allow any remaining oil to drain into the catch pan.
Sub-step 2: Apply a thin layer of fresh oil to the rubber gasket of the new oil filter.
Sub-step 3: Install the new oil filter by hand, tightening it according to the manufacturer’s specifications (usually hand-tight plus a quarter turn).

4. Inspect and Replace Oil Pump

Sub-step 1: Remove any necessary components to access the oil pump (refer to the vehicle's service manual).
Sub-step 2: Disconnect the oil pump from the engine and inspect for wear or damage.
Sub-step 3: Install a new oil pump if the old one is defective, ensuring proper alignment and torque specifications are followed.

5. Final Checks

Sub-step 1: Start the engine and allow it to warm up while monitoring the oil pressure gauge.
Sub-step 2: Check for leaks around the oil filter and oil pump area.
Sub-step 3: Recheck the oil pressure to ensure it is within the normal range.
