No, the readings are only for tail pipe style tests(asm and tsi). OBDII gets pass or fail for: bulb check, MIL command, and OBD readiness...and of course gas cap. Yeah a failed emissions will not keep you from getting a ticket, It's up to the cop whether or not they want to give you one. I have had 3+ customers get "expired tag" tickets @ my emission station parking lot in the last 2 months and one of them got a ticket in the actual lane where I test the cars! Thats bullcrap!! dam cops.
