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
