Solution
1. Preparation
  • Gather tools: OBD-II scanner, socket set, torque wrench, multimeter.
  • Ensure the vehicle is parked on a level surface and the ignition is off.
2. Address Error Codes
  • Use the OBD-II scanner to read and document all stored error codes.
  • Clear the codes and take the vehicle for a test drive to see if the codes reappear.
3. Inspect the Gas Cap
  • Remove the gas cap and inspect it for cracks or wear.
  • Clean the sealing surface on the filler neck.
  • Replace the gas cap if it is damaged and ensure it clicks securely when reinstalled.
4. Check for Vacuum Leaks
  • Visually inspect hoses and connections for signs of wear or damage.
  • Use a smoke machine or brake cleaner to detect leaks in the vacuum system.
  • Repair or replace any damaged hoses as needed.
5. Examine Electrical Connections
  • Disconnect the battery to ensure safety.
  • Inspect wiring and connectors for corrosion or damage, particularly around sensors indicated by error codes.
  • Clean connections and repair or replace wires as needed.
6. Test Battery and Charging System
  • Use a multimeter to check battery voltage; it should read between 12.4 and 12.7 volts when the engine is off.
  • Start the engine and check voltage; it should rise to between 13.7 and 14.7 volts.
  • Replace the battery if it fails to hold charge or if voltage readings are outside of the specified range.
