Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is parked on a flat surface and the ignition is off.
  • Safety warning: Disconnect the battery before working on electrical systems.
2. Scan for Codes
  • Use an OBD-II scanner to connect to the vehicle’s diagnostic port.
  • Record any error codes displayed for further troubleshooting.
  • Clear the codes and monitor if the check engine light returns.
3. Inspect Gas Cap
  • Remove the gas cap and check for cracks or damage.
  • Clean the gas cap and the sealing surface on the filler neck.
  • Replace the gas cap if necessary, ensuring it clicks securely when reattached.
4. Check Engine Oil and Coolant
  • Remove the dipstick, wipe it clean, and reinsert it to check the oil level.
  • If oil is low, top it off with the manufacturer-recommended oil type.
  • Check coolant level in the reservoir; add coolant if below the recommended level.
5. Inspect Electrical Connections
  • Visually inspect battery terminals and connections for corrosion or looseness.
  • Clean any corrosion using a wire brush and reconnect securely.
  • Test the battery with a multimeter; replace if voltage is below 12.4 volts.
6. Monitor and Test Drive
  • Start the vehicle and allow it to reach operating temperature.
  • Take the vehicle for a short test drive while monitoring for any unusual symptoms.
  • Check if the check engine light reappears after the drive.
