Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, oil pressure gauge, oil filter wrench, multimeter, torque wrench, safety glasses, and gloves.
Ensure the vehicle is on a level surface and the engine is cool before beginning work.

2. Check and Add Oil

Sub-steps:
1. Remove the oil dipstick and wipe it clean.
2. Reinsert the dipstick and remove it again to check the oil level.
3. If the oil level is low, add the appropriate type and amount of engine oil as specified in the owner's manual.
4. Start the engine and check the oil pressure warning light after a few minutes.

3. Replace the Oil Filter

Sub-steps:
1. Use an oil filter wrench to remove the oil filter.
2. Before installing the new filter, apply a thin layer of new oil to the rubber gasket on the new filter.
3. Install the new oil filter and tighten it according to manufacturer specifications (usually hand-tight plus a quarter turn).

4. Test and Replace the Oil Pump (if necessary)

Sub-steps:
1. Disconnect the negative battery terminal for safety.
2. Remove the oil pan to access the oil pump.
3. Inspect the oil pump for wear and ensure the pick-up tube is clear.
4. If the pump is damaged, replace it with a new one and ensure proper alignment during installation.

5. Reassemble and Refill Oil

Sub-steps:
1. Reinstall the oil pan and tighten bolts to the specified torque.
2. Refill the engine with the recommended oil type and quantity through the oil filler cap.
3. Reconnect the negative battery terminal.
