Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent any accidental electrical issues.

2. Check and Top Off Oil

Remove the dipstick and wipe it clean.
Reinsert and remove the dipstick again to check the oil level.
- If low, add the recommended oil type (SAE 5W-20 or as specified in the owner's manual) to the engine through the oil filler cap until the correct level is reached.

3. Inspect and Replace Oil Filter

Locate the oil filter and use an oil filter wrench to remove it.
Apply a small amount of new oil to the rubber O-ring of the new filter.
Install the new oil filter, ensuring it is snug but not overtightened.

4. Oil Pressure Sending Unit Inspection

Locate the oil pressure sending unit (usually near the oil filter).
Disconnect the electrical connector and remove the unit using a socket.
Inspect the unit for any signs of damage or wear and replace it if necessary.
Reinstall the new unit, tightening it to the manufacturer's specifications.

5. Oil Pump Inspection (if necessary)

If low oil pressure persists, inspect the oil pump.
Remove the oil pan to access the oil pump (may require removing other components).
Inspect the oil pump for wear or damage and replace if necessary.
Reinstall the oil pan with a new gasket and torque to specification.
