Solution
1. Preparation
  • Gather tools: OBD-II scanner, socket set, multimeter, torque wrench.
  • Ensure the vehicle is parked on a level surface and the engine is cool.
  • Disconnect the negative battery terminal to prevent electrical shorts.
2. Addressing Error Codes
  • Connect the OBD-II scanner to the vehicle's diagnostic port.
  • Record any error codes and refer to the service manual for definitions.
  • Clear the error codes and monitor if they reappear after a test drive.
3. Inspecting the Gas Cap
  • Remove the gas cap and inspect for cracks or a damaged seal.
  • Replace the gas cap if any damage is found.
  • Tighten the gas cap until it clicks to ensure a proper seal.
4. Replacing Spark Plugs and Ignition Coils (if necessary)
  • Remove the engine cover (if applicable) using a socket set.
  • Disconnect electrical connectors from the ignition coils.
  • Remove the ignition coils using a socket set.
  • Remove the old spark plugs using a spark plug socket and replace with new ones, ensuring they are torqued to manufacturer specifications (typically 15-20 ft-lbs).
  • Reinstall ignition coils and reconnect the electrical connectors.
5. Testing Electrical System
  • Use a multimeter to check the battery voltage; it should read between 12.4V-12.7V with the engine off.
  • Start the engine and check the voltage again; it should be between 13.7V-14.7V.
  • If voltage is outside these ranges, inspect the alternator and battery connections.
