Set Condition

WARNING: This page is about a different car, the 2014 Dodge Journey. However, it is still accessible from the selected car via links, so may be relevant.

The Powertrain Control Module (PCM) detects that the Oxygen Sensor 1/2 voltage is greater than the maximum acceptable value for a specific amount of time, based on Oxygen Sensor 1/2 Heater temperature. The DTC will set as Pending after one trip and Active after two trips. Three good trips to turn off the MIL.
