Are you sure the DTC isn't P0171?
B and C DTC prefixes are for Body and Chassis.
Here is a good resource for information:

Are you seeing any actual faults related to these mystery codes? DSC not available, etc.?
Working from potentially faulty memory, but I thought our cars sometimes generate “phantom” codes that mean nothing. For example, I thought some HVAC sensor or actuator was deleted on later models, but the software was never updated. The computer would throw a fault code for the missing component, but the system worked fine. The “fault” was never annunciated to the driver, but a mechanic could see it if he went digging, even though it means nothing.

Only a few that I can confirm. The power steering codes return immediately and the steering is pretty stiff at low speeds so I think that one is legit. Some of the others are evidently so obscure that no one even knows what they are so I don't know what to look for. The parking sensor is probably legit although I haven't checked it because it's a low priority. I think I'll focus on the mechanicals for now and, once all that is sorted out, maybe try to chase some of the ghost codes down.

I don’t have a scanner capable of reading body codes, but note the symptoms presented due to a failed sensor.
