Meaning of fuel system loop status
• The following information is displayed on the tester.
— Feedback stops: ECT is lower than the determined feedback zone.
— Feedback operating: HO2S being used for feedback is normal.
— Feedback stops: Open loop due to driving condition
— Feedback stops: Open loop due to detected system fault
— Feedback operating: Malfunction occurred in HO2S (rear) system
