When Monitored

WARNING: This page is about a different car, the 2017 RAM 2500 HD. However, it is still accessible from the selected car via links, so may be relevant.

First Diagnostic:
At ignition on, engine not running, after an 8 hour cold soak. The ambient air temperature must also be above -6.7°C (20°F).
Second Diagnostic:
After a PM Sensor regeneration event and the PM Sensor has transitioned into measurement mode, and vehicle speed is above 3 MPH. A regeneration event will occur when the Exhaust Gas Temperature Sensor 1/5 (SCR Catalyst Outlet) reading goes above 200°C (392°F), and there are no other PM Sensor related DTCs. The ambient air temperature must also be above -6.7°C (20°F). A steady state drive cycle will run this diagnostic.
