Solution

1. Preparation

Gather tools and materials:
- Oil pressure gauge
- Socket set
- Oil filter wrench
- New oil filter
- Engine oil (as specified in the owner's manual)
Make sure the vehicle is parked on a level surface and the engine is cool.

2. Check Oil Level

Remove the dipstick, wipe it clean, reinsert, and remove again to check the oil level.
If oil is low, add the appropriate type and amount of oil as per the manufacturer's specifications.

3. Replace Oil Filter

Tools Required: Oil filter wrench, socket set
Locate the oil filter and use the oil filter wrench to remove it.
Prepare the new oil filter by applying a small amount of new oil to the rubber gasket.
Install the new oil filter and tighten it by hand, ensuring a snug fit without over-tightening.

4. Change Engine Oil

Tools Required: Socket set, oil catch pan
Drain the old oil by removing the drain plug located at the bottom of the oil pan (ensure the engine is cool).
Allow the oil to fully drain into the catch pan.
Reinstall the drain plug and torque to the manufacturer's specifications.
Fill the engine with new oil through the oil filler cap, using the correct type and amount.

5. Test Oil Pressure

Tools Required: Oil pressure gauge
Remove the oil pressure switch/sensor and install the mechanical oil pressure gauge.
Start the engine and observe the oil pressure reading.
If the pressure is within the manufacturer's specifications, replace the oil pressure switch/sensor if necessary.

6. Reassemble and Check

Reinstall any components removed during the diagnostic process.
Start the engine and check for leaks around the oil filter and drain plug.
Monitor the oil pressure warning light; it should remain off if the issue is resolved.
