The Powertrain Control Module (PCM) detects a condition where the downstream O2 Sensor has remained in open loop fuel control, from a start-up condition, longer than a calibrated amount of time, when conditions would have otherwise expected closed loop operation. Two trip fault. Three good trips to turn off the MIL.
