Thank you for writing in. It is impossible to tell what issues are stopping the vehicle from passing the emissions test. The sensors that are stopping the vehicle from passing need to be addressed, or we need to find out what those sensors have in common and determine if there is an underlying cause. If you can write in with more information on those sensors, we may be able to help a little more. At this point, it sounds like only further testing will tell. Good luck!
