Cm870 no accelerator pedal

[SunnySide]

After doing a few of the calibration \ tests with insite , I lost accelerator pedal voltage. If I remember right, the last one I did was the injector test where it has you crank for a while with no start. Truck starts and idles fine but no pedal voltage at all. Zero volts. My only fault code has been egr related. I get no voltage change or error codes when pulling on wires or disconnecting plugs. It does not acknowledge throttle position sensor. I tried another with the same response. I put a meter to the switch in question and it does showing varying resistance reading when switch is actuated. I do have 5v making it to the pedal.
