Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is parked on a level surface and the engine is cool.
  • Disconnect the battery before starting any electrical work.
2. Addressing Codes
  • Based on the OBD-II trouble codes retrieved, follow the specific diagnostic procedure for each code. For example:
    • If the code indicates a faulty oxygen sensor, locate the sensor, disconnect the electrical connector, and replace the sensor with a new one.
3. Gas Cap Inspection
  • Remove the gas cap and inspect for cracks or damage.
  • Clean the sealing surface on the filler neck.
  • Replace the gas cap if needed, ensuring it clicks securely when reinstalled.
4. Spark Plug and Ignition Coil Replacement
  • Remove the engine cover if applicable.
  • Disconnect the electrical connectors from each ignition coil.
  • Remove the ignition coils using a socket wrench.
  • Replace spark plugs with new ones, ensuring the correct gap.
  • Reinstall ignition coils and reconnect the electrical connectors.
5. Fuel System Check
  • Connect a fuel pressure gauge to the fuel rail.
  • Start the engine and observe the pressure reading.
  • If pressure is below the specified range, check the fuel filter and fuel pump functionality.
