WE HAVE A 08 F550 WITH 6.4. WE HAD DPF CLEANED AND INSTALLED NEW SENSORS, ALL 3. BUS WAS DROVE FOR ABOUT 200 MILES AND WE LOST THROTTLE RESPONSE. BROUGHT BUS BACK TO SHOP AND CHECKED CODES AND HAD CODES P2002 AND P244A. BUS SEEMS TO OPERATE NORMALLY NOW. WHAT DO WE NEED TO DO TO FIX THESE CODES?

 

I am thinking you might try to erase the codes and see what happens.

I am also wondering if you need to have the pcm reset for the values since you cleaned the dpf.
