Detection Condition

DTC is set when rear HO2S input is more than .45 volt for 6 seconds during decelerations (fuel cut). This is a Continuous Monitor (CM). MIL illuminates if PCM detects malfunction condition in 2 consecutive drive cycles. Pending code is available if PCM detects malfunction condition during first drive cycle. Freeze Frame Data is available and DTC is stored in PCM memory.
