I have been doing low enhanced emissions testing in upstate ny for several years now and as far as our cars are concerned it is just a visual inspection i.e. converter,egr valve,gas fill restricter,gas cap,ect..1996 and up vehicles with obd2 connectors will be plugged into the inspection machine and readiness monitors will be checked. if no service engine soon light on and monitors are set vehicle passes. the government feels the vehicle is smart enough to know if it is running clean or within set parameters.
