Solution
1. Preparation
  • Gather all necessary tools and parts.
  • Ensure the vehicle is parked on a level surface and the ignition is off.
  • Disconnect the battery negative terminal to prevent electrical shorts.
2. Check Oil Level
  • Reconnect the battery.
  • Using the dipstick, pull it out, wipe it clean, reinsert it fully, and then remove it again to check the oil level.
  • If low, add the appropriate oil type specified in the vehicle manual.
3. Inspect Oil Filter
  • If the oil filter was recently changed, ensure it is properly seated.
  • Using an appropriate wrench, remove the oil filter.
  • Inspect the rubber O-ring for damage or remnants of the old filter.
  • Replace with a new filter and tighten to the manufacturer's specifications (typically hand-tight plus 3/4 turn).
4. Check Oil Pressure Sensor
  • Locate the oil pressure sensor, usually found near the oil filter or on the engine block.
  • Inspect the electrical connector for damage or corrosion.
  • If necessary, replace the oil pressure sensor by unscrewing it with a socket wrench and installing a new one.
5. Clear Codes and Test
  • Use the OBD-II scanner to clear any stored codes.
  • Start the engine and let it idle. Observe for any illuminated warning lights or unusual sounds.
  • Conduct a short test drive to ensure the check engine light does not reappear.
