Just swapped in a new exhaust control valve from autohaus, getting the same P048C - 000.

Why I suspect it is a cable:

-The 000 part which is 'implausible signal', (aka nothing?)
-I moved the flap on old part and it feels same as new.
-Before replacement I disconnected wire while troubleshooting. I oiled the external spring, worked it a little and the CEL went out. CEL came back on by itself shortly before part replace.

So is it a bad wire or connector? Or.... what?
If so, leads to threads on continuity/power check pls. Yes I did a search.

Attached is the fault sections of the fresh scan. The clogged filter is likely due to it not being able to regen because of flap. The 'EGR system' fault is new, was not on scan from a week ago.

Thanks!!
