When Monitored

WARNING: This page is about a different car, the 2013 RAM 1500. However, it is still accessible from the selected car via links, so may be relevant.

There are several different catalyst efficiency monitoring windows. Each specific window has several different enable conditions. The best opportunity for the catalyst efficiency monitor to run is the engine warmed up above 60°C (140°F), engine speed between approximately 1000 RPM and 2500 RPM, vehicle speed between 3 mph and 80 mph, under moderate engine load, and no other O2 Sensor circuit faults active.
