I remember reading something in another thread that said for PA drivers, if after 3 attempts to scan your car it still can't find it then they can't fail you for it. It went something like that, I think. I'll see if I can dig it up for you......

but you didnt hear that from me

make sure you have positive and ground at the right terminals and check all the other pins out, you should be able to get that information from alldata, or mitchell

My bad, your 1st post seemed to indicate it was an inspection related issue. Hope you can figure it out......

As someone mentioned earlier, it seems like one of the wires may have a bad connection. It might be hard to trace the wires, but you could always use a multi-meter to test it at each end, or just run a new length of wire to the ECU.
