Set Condition

WARNING: This page is about a different car, the 2024 Jeep Grand Cherokee L. However, it is still accessible from the selected car via links, so may be relevant.

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.
