Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is parked on a level surface and the engine is cool.
2. Scan for Error Codes
  • Connect the OBD-II scanner to the vehicle's diagnostic port.
  • Retrieve and document the error codes.
  • Research codes to determine potential issues.
3. Inspect and Replace Components
  • Check the Gas Cap:

    • Remove and inspect the gas cap for cracks or damage.
    • If damaged, replace it with a new one.
  • Inspect Vacuum Hoses:

    • Visually inspect all vacuum hoses for signs of wear or disconnections.
    • Replace any damaged hoses with OEM parts.
  • Check Air Filter:

    • Open the air filter housing.
    • Remove the air filter and inspect for dirt and blockages.
    • Replace with a new air filter if necessary.
4. Battery and Charging System Check
  • Use a multimeter to check the battery voltage (should be around 12.6V for a healthy battery).
  • If voltage is low, recharge or replace the battery.
  • Inspect the alternator for proper operation.
5. Clear Error Codes
  • After completing repairs, use the OBD-II scanner to clear the error codes.
  • Perform a test drive to ensure the check engine light does not return.
