Is it true the SMOG MACHINES, will continue
to say , "NO CONNECTION", making it
impossible to get my 2016 sticker . Because
I don't have the orignal radio, that came with
the car, when I purchased it in 2009
Nope your radio is a separate system and has nothing to do with engine management. If your getting a no connection through the port then look for a blown fuse, if none are found then you are going to have to start tracing down circuits to find the open one in the port harness assembly. A wiring diagram would really be helpful on this problem. If you are going to find it yourself I would get a good shop manual with wiring diagrams, if you can't find one then try your local library's reference section for a manual you can photocopy.
