    In response to 355Cheyenne

Thanks again. If this ECM was replaced, that means there was an ECM factory programmed to operate without a sensor. Is there a list of the factory proms somewhere that would indicate what programming it has (I.e. AWAK is this setup while ASHE is that setup). This guy took very good care of his truck (it was a hose failure and lack of attention to the SES that blew the motor.), I'd be surprised if he did anything like remove the ESC and knock sensor. He was the original owner, and the truck only has 80k miles. Replacing the ECM is one thing, completely cutting out a set of equipment instrumental to the engine running properly is something entirely different.
I am getting/have gotten no codes since the engine was replaced.
