Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is parked on a level surface and the engine is cool.
  • Disconnect the negative battery terminal to prevent electrical shorts.
2. Code Retrieval
  • Connect the OBD-II scanner to the vehicle's diagnostic port.
  • Turn the ignition to the "ON" position without starting the engine.
  • Retrieve and document the error codes for further analysis.
3. Inspect and Replace Faulty Components

A. Gas Cap Inspection

  • Remove the gas cap and inspect for cracks or wear.
  • Replace the gas cap if damaged or if it does not seal properly.

B. Air Filter Replacement

  • Remove the engine cover if necessary.
  • Unclip the air filter housing and remove the old air filter.
  • Install a new air filter, ensuring it fits snugly and seals properly.

C. Ignition System Check

  • Remove spark plug wires and unscrew the spark plugs.
  • Inspect spark plugs for wear; replace if fouled or damaged.
  • Test ignition coils for resistance as specified in service manual; replace if outside specifications.
4. Fuel System Check
  • Attach a fuel pressure gauge to the fuel rail.
  • Turn the ignition to "ON" to check for proper fuel pressure; refer to service manual for specifications.
  • Inspect for any fuel leaks around the injectors and fuel lines; tighten or replace as needed.
5. Exhaust System Examination
  • Visually inspect the exhaust system for any visible holes or rust.
  • Use a smoke machine to check for leaks in the exhaust system, particularly at gaskets and connections.
