Solution
1. Preparation
  • Gather tools: OBD-II scanner, socket set, multimeter, torque wrench, and basic hand tools.
  • Ensure the vehicle is parked on a level surface and the engine is off.
2. Retrieve and Analyze Codes
  • Connect the OBD-II scanner to the vehicle's diagnostic port.
  • Turn on the ignition without starting the engine.
  • Record any error codes displayed and interpret them using a repair manual or online resources.
3. Inspect and Replace Components

a. Gas Cap

  • Check the gas cap for cracks or missing seals.
  • If damaged, replace it with a new gas cap.
  • Torque to specifications, typically around 15-20 ft-lbs.

b. Spark Plugs and Ignition Coils

  • Remove the ignition coils using a socket set.
  • Inspect the spark plugs for wear or damage.
  • Replace spark plugs with OEM specifications (gap them as required).
  • Reinstall ignition coils and torque to manufacturer specifications (usually around 10-15 ft-lbs).

c. Air Intake System

  • Inspect the air filter; replace if dirty or clogged.
  • Check for vacuum leaks in hoses and connections.
  • Replace any damaged hoses or connections.

d. Exhaust System

  • Check for visible exhaust leaks or blockages.
  • If found, replace necessary components, such as gaskets or pipes.
4. Clear Codes and Test
  • Use the OBD-II scanner to clear the error codes.
  • Take the vehicle for a test drive to ensure the check engine light remains off.
