[2nd Method]

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 3500 RPM.
    NOTE:
    • If equipped with Manual Transaxle, shift the gear properly for keeping the engine speed above 3500 RPM.
