Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, oil pressure gauge, oil filter wrench, torque wrench.
Safety Warnings: Disconnect the battery before working on electrical systems. Allow the engine to cool before performing any maintenance.

2. Check and Replace Engine Oil

Sub-steps:
1. Open the hood and locate the oil filler cap.
2. Remove the oil filler cap and check the oil level using the dipstick.
3. If the oil level is low, add the recommended oil type (refer to the owner's manual).
4. If the oil is dirty or contaminated, drain the old oil using a socket set to remove the oil drain plug.
5. Replace the oil filter using an oil filter wrench.
6. Reinstall the oil drain plug and refill with new engine oil, ensuring it meets manufacturer specifications.

3. Inspect and Replace Oil Pump (if necessary)

Sub-steps:
1. If low oil pressure persists, remove the oil pan using a socket set.
2. Inspect the oil pump for wear or damage.
3. If the pump is faulty, replace it with a new one, ensuring it is properly aligned.
4. Reassemble the oil pan with a new gasket, torqueing the bolts to the manufacturer specifications.

4. Final Checks

Reconnect the battery.
Start the engine and check for any leaks around the oil filter and drain plug.
Monitor oil pressure readings using the gauge.
