Solution

1. Preparation

Gather tools and materials: OBD-II scanner, socket set, torque wrench, oil filter wrench, new oil filter, new engine oil, rags, and a container for old oil.
Ensure the vehicle is on a level surface and the engine is cool.

2. Check and Top Off Engine Oil

Remove the dipstick and wipe it clean with a rag.
Reinsert the dipstick and remove it again to check the oil level. If low, add the appropriate type and amount of engine oil as specified in the owner's manual.
Dispose of any old oil properly if drained.

3. Inspect and Replace Oil Filter

Use the oil filter wrench to remove the old oil filter. Ensure the rubber O-ring comes off with it.
Lubricate the rubber O-ring of the new oil filter with a bit of new oil.
Install the new oil filter by hand until snug, then tighten according to manufacturer specifications (typically 3/4 turn after contact).

4. Check Oil Pressure Sensor

Locate the oil pressure sensor, typically found near the oil filter or on the engine block.
Disconnect the electrical connector from the sensor.
Use a multimeter to test the sensor's resistance based on specifications in the service manual.
If faulty, replace the oil pressure sensor.

5. Inspect and Replace Oil Pump (if necessary)

If low oil pressure persists, remove the oil pan by unscrewing the bolts (use a torque wrench for reinstallation).
Check the oil pump for wear, cracks, or damage. Replace if necessary, following the manufacturer's installation procedures and torque specifications.
