Have you measured the throttle switch resistance values with a 
multimeter and compared them to the Bentley specs? Also, a power 
(boost) loss related to throttle potentiometer can be a symptom of a 
simple misadjustment of the switch position (altho I don't know if 
that would also throw the 2212 code).

It does requires some fiddling to get the meter probe tips positioned 
on the proper connector terminals, but before going to the trouble 
and expense of replacing the part, you ought to do the measurements 
to verify the internal problem.
