Need help with DTC chassis codes, tps related..?

I ran a dtc check using engineering mode, came up with c41500 and c41581, any ideas guys? Could it be the tps, I have noticed surges in throttle response lately. Im trying to find a new throtlebody with tps to try out, but no luck. Anyone know where to find one? All I find are for the GT.

These codes are also stored on mine...

Can anyone provide some insight?

Ever figure this out?

I don't believe those are codes for any failures, but rather programming confirmation codes used by engineers to verify successful completion of as built programming. I would be very careful when in the engineering test modes to not change any coding that you are not 100% sure of what it is for, or you have not been instructed to do so by Ford tech.

Those are most definitely not computer DTC codes reporting a failure of a component or system.

Change at your own risks.
