Well, P1223 is for a TPS and it looks like C1201 is related to a wheel speed sensor? Very unrelated to each other.
The TPS is a fairly easy fix, but the WSS is obviously more involved. You need to finger out which wheel is throwing the code...
More info may glean more suggestions

The "C" codes are manufacturer specific DTC codes.
It looks like C1223 is as follows:
When the VSC sees a problem in the ABS System it will set C1223. Looks like problem area is usually ABS(skid control) ecu.
C1201
Looks like problem area is usually ecu.
So to summarize,
C1201 says there is a problem at the ECU level, and driling down C1223 says there is an issue at the VSC ecu level. There should be another code stored below those. The light went off though so I may need to wait until next time.
