Solution
1. Preparation
  • Gather necessary tools and parts.
  • Disconnect the battery to ensure safety while working on electrical components.
2. Address Fault Codes
  • Sub-step 1: Use the OBD-II scanner to read and document error codes.
  • Sub-step 2: Research the codes to determine potential causes and fixes.
3. Inspect and Replace Components
  • Sub-step 1: If the gas cap is faulty, replace it with a new OEM or equivalent part.
  • Sub-step 2: For vacuum leaks, replace damaged hoses or fittings as necessary.
  • Sub-step 3: If the MAF sensor is faulty, carefully remove it and replace it with a new one, ensuring proper alignment.
  • Sub-step 4: If spark plugs or ignition coils are worn, replace them as per manufacturer specifications, ensuring proper torque on installation (typically around 13-15 lb-ft for spark plugs).
4. Clear Codes and Test
  • Sub-step 1: Reconnect the battery and use the OBD-II scanner to clear the codes.
  • Sub-step 2: Start the engine and observe if the check engine light reappears after a test drive.
