Set Condition

WARNING: This page is about a different car, the 2016 Dodge Journey and 2015 Dodge Journey. However, it is still accessible from the selected car via links, so may be relevant.

The Powertrain Control Module (PCM) monitors the Adaptive Memory factor (a combination of Short Term Adaptive and Long Term Adaptive). If the total fuel addition exceeds a calibrated threshold for an extended period, a fuel system lean fault is stored. If the total fuel subtraction exceeds a calibrated threshold, a fuel system rich fault is stored. Two Trip Fault. Three good trips to turn off the MIL.
