Engine speed is between 1, 000-2, 500 RPM to enable the catalyst diagnostic. Once the engine speed is in range, the engine speed must be between 1, 110-2, 375 RPM to keep the test enabled.
Accelerator pedal position is at most 100 %.
Ethanol estimation is not active.
Evaporative emission (EVAP) purge is not active.
Post HO2S heaters are ON for greater than 60 s.
Mass air flow (MAF) is between 3-11 g/s.
System voltage is between 10-32 V.
Vehicle speed is between 42-80 km/h (26-50 MPH) to enable the catalyst diagnostic. To keep the test enabled the vehicle speed is between 39-82 km/h (24-51 MPH).
Catalyst calculated temperature is between 500-980°C (932-1, 796°F).
Engine is operating in closed loop.
Engine is operating in decel fuel cut off (DFCO).

This diagnostic attempts one test during each valid OFF-idle period once the above conditions have been met. This diagnostic attempts up to 3 tests during each drive cycle.
