Solution
1. Preparation
  • Gather necessary tools and parts.
  • Disconnect the battery by removing the negative terminal to ensure safety while working on electrical components.
2. Addressing Error Codes
  • Use the OBD-II scanner to retrieve and document error codes.
  • Research the codes to identify specific systems or components that may require attention.
3. Inspect and Replace Gas Cap (if faulty)
  • Remove the existing gas cap.
  • Inspect for cracks or damage; replace if necessary.
  • Ensure that the new gas cap is tightened securely.
4. Air Filter Inspection and Replacement
  • Locate the air filter housing and remove the cover.
  • Inspect the air filter; replace it if it is dirty or clogged.
  • Reassemble the air filter housing securely.
5. Check Battery and Alternator
  • Use a multimeter to check the battery voltage (must be around 12.6 volts when fully charged).
  • Start the vehicle and check the alternator output (should be between 13.7 to 14.7 volts).
  • Replace the battery or alternator if readings are below specifications.
6. Clear Error Codes
  • Use the OBD-II scanner to clear the error codes after repairs.
  • Reconnect the battery terminal.
