Not exactly true. You don't have to have the CEL on and still fail emissions. Like I was saying, if all of the monitors don't set, then a soft code (no CEL light) P1000 will set. 7 monitors have to set, you can get away 2 not setting. Most of the time, evap takes the longest to set because it has to cold soak (not running) for at least 24 hours
