Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is parked on a flat surface and the engine is off.
  • Disconnect the battery to ensure safety during repairs.
2. Address Error Codes
  • Connect the OBD-II scanner and read the stored error codes.
  • Research the codes to determine which components or systems are affected.
  • Clear the codes and see if they return after a test drive.
3. Inspect and Repair Components
  • Gas Cap Check:
    • Remove the gas cap and inspect for cracks or damage.
    • Replace if necessary, ensuring a tight seal when reattached.
  • Sensor Inspection:
    • Locate the mass airflow sensor and oxygen sensors.
    • Clean or replace as needed based on visual inspection and functionality tests.
  • Battery Check:
    • Inspect battery terminals for corrosion, clean if needed.
    • Test battery voltage; replace battery if voltage is below specifications (typically 12.6 volts).
4. Fluid Checks and Changes
  • Fluid Levels:
    • Check engine oil, coolant, and transmission fluid levels.
    • Top off or replace fluids that are low or dirty.
  • Oil Change:
    • If due for service, perform an oil change using manufacturer-recommended oil.
5. Reassemble and Test
  • Reconnect the battery and ensure all connections are secure.
  • Start the engine and monitor for any abnormal sounds or behaviors.
  • Take the vehicle for a short test drive to ensure the check engine light does not return.
