Solution
1. Preparation
  • Gather tools: OBD-II scanner, socket set, torque wrench, multimeter, and safety glasses.
  • Park the vehicle on a level surface and engage the parking brake.
  • Disconnect the battery to ensure safety while working on electrical components.
2. Address Error Codes
  • Connect the OBD-II scanner to the diagnostic port and read the stored trouble codes.
  • Note down the codes and refer to a repair manual or database to understand the implications of each code.
3. Inspect and Repair Components
  • Gas Cap Inspection

    • Remove the gas cap and inspect for cracks or a damaged sealing ring.
    • Replace the gas cap if necessary, ensuring it clicks securely upon installation.
