WARNING: This page is about a different car, the 2024 Kia Sorento. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: The 2nd method should be performed only if the 1st method fails (the misfire-related codes recur).
  1. Start the engine and keep the engine running at idle for 2 minutes.
  2. Drive the vehicle for over 20 minutes, keeping the engine speed above 3, 500 rpm.
    NOTE: If equipped with manual transaxle, shift the gear properly for keeping the engine speed above 3, 500 rpm.
