P0606

[ProTouring442]

Wasn't sure where to put this, so...

Tried to drive my LY5 powered Jeep for the first time today. Everything works until it sets the code P0606. After the code is set, the gas pedal stops working.

Drive very slowly, the code won't set. Try to drive a bit faster, and it sets the code.

The code is listed as "ECM/PCM Processor Fault"

"The Engine Control Module (ECM) continuously monitors its internal memory status, internal circuits, and output signals to the throttle actuator. This self−check insures that the ECM is functioning properly. If any malfunction is detected, the ECM will set the code and illuminate the engine light."


I am in touch with the place who programmed it, but I wanted opinions as to whether there might be anything I should look for outside the ECM.

Thanks!
