Solution

1. Preparation

Gather tools including an OBD-II scanner, socket set, oil filter wrench, and torque wrench.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Check and Top Off Oil Level

Remove the dipstick and wipe it clean.
Reinsert the dipstick and pull it out again to check the oil level.
If low, add the recommended oil type (e.g., 0W-20) until the level is correct.

3. Inspect and Replace Oil Filter

Use an oil filter wrench to remove the old oil filter.
Before installing the new filter, apply a little oil to the rubber gasket of the new filter to ensure a good seal.
Install the new oil filter and tighten it according to the manufacturer's specifications (usually hand-tight plus 3/4 turn).

4. Test Oil Pressure Sending Unit

Disconnect the electrical connector from the oil pressure sending unit.
Using a multimeter, check for continuity and proper voltage according to the specifications in the service manual.
Replace the sending unit if it is faulty.

5. Inspect and Replace Oil Pump (if necessary)

If the oil pressure sending unit is functional, remove the oil pan (drain the oil first).
Inspect the oil pump for any signs of wear or damage, and replace it if necessary.
Reinstall the oil pan using a new gasket and torque to the specified values.
