IF you fail with a catalyst code it will have to have the catalyst monitor set to ready on the next retest & no p0420/p0430.

If you go for a repair wavier there are more rules that apply also.

 

"Well I noticed this post was a bit old but I can tell you as of 5-25-12 you CAN get by with evap control sys. "NOT READY" I just passed my emissions here in Il."

How about it now? Still true?

 

Conformed. One Not-Ready EVAP sensor still can pass IL emission test.
