01–02
Meaning of fuel system loop status
• The following information is displayed on the tester.
— Feedback operating: HO2S being used for feedback is normal.
— Feedback stops: ECT is lower than the determined feedback zone.
— Feedback stops: Open loop due to driving condition.
— Feedback stops: Open loop due to detected system fault.
OBD-II Diagnostic Trouble Code (Mode 03)
• The following DTCs have been adopted.
— P0116, P0134, P0137, P0411, P050A
• Differences between the 2006 MY and 2005 MY DTCs are shown below.
