Meaning of fuel system loop status
•  The following information is displayed on the tester.
―  Feedback operating: A/F sensor, 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.


On-board system readiness test

•  The items supported by the on-board system readiness test are shown below.
Continuous monitoring system
―  Misfire monitoring
―  Fuel system monitoring

Sending Continuous Monitoring System Test Results (pending code) (Mode 07)

•  These appear when a problem is detected in a monitored system.
1 drive cycle type
•  If any problems are detected in the first drive cycle, pending codes will be stored in the PCM memory, as well as DTCs.
•  After pending codes are stored, if the PCM judges that the system is normal in any future drive cycle, the PCM deletes the pending codes.
2 drive cycle type
•  The code for a failed system is stored in the PCM memory in the first drive cycle. If the problem is not found in the second drive cycle, the PCM judges that the system returned to normal or the problem was mistakenly detected, and deletes the pending code. If the problem is found in the second drive cycle too, the PCM judges that the system has failed, and stores the pending codes, and the DTCs.
•  After pending codes are stored, if the PCM judges that the system is normal in any future drive cycle, the PCM deletes the pending codes.
