Solution
1. Preparation
  • Gather tools and parts needed for repair.
  • Disconnect the vehicle's battery to ensure safety while working on electrical components.
2. Inspect and Replace Gas Cap
  • Sub-steps:
    • Remove the gas cap and visually inspect for cracks or damage.
    • If damaged, replace with a new OEM gas cap.
    • Securely tighten the new gas cap until it clicks.
