downloaded test results from scan tool.
here's the file:
recently, had a/c serviced. when picked it up, it had this code (didnt have
it before took in.)
the a/c shop siad that6 compressor wasnt running because a/c/ system empty.
so, they injected dye, leak tested it with a light , found no leaks, and
recharged the system.
when i picked up the truck (via lockout and 2nd key), truck had CEL.
P0430 , and the test results in the file.
i dont know what recharging the a/c would have to do with inefficiency in
the 2nd bank, but maybe just a coincidence??
what to check ?
