The steering sensor is a ring magnet located at the bottom of the steering wheel. It is used to determine the direction you want the car to go and is checked against the yaw sensors to determine if you are in a skid or not. It produces a +/- 5vDC output from stop to stop on the steering wheel.
It is a PITA to replace since you have to remove the steering column to get to it. That said, however, there is a distinct possibility that it is a ground and not a failure of the part. I would urge you to check, by removing, cleaning and relanding, all your ground connections. My error was corrected with the ground on the rear above the diff and the left front on the chassis. Its been awhile though, so check them all. If you don't have the service manuals for your car, now would be a great time to get them. Unless you're handy and don't mind tearing the column apart, find a dealer you can trust and have them take a crack at it.

HTH,

Joe

Most of the time this code results from disconnecting the steering rack, rotating the steering wheel, then reconnected. Any sort of work performed recently that could be related?

You are right I did disconnect the steering rack and moved the steering wheel. Did it mess up the sensors and how can it be fixed?

You have to measure the voltage at the steering wheel sensor (located at the firewall on the steering post. The voltage in the correct position will be about 2.4-2.6V. The light blue wire is the the one to measure voltage. Be prepared to do upside down twisting to get to it.) More than likely it will read 0.26V or 4.9V or close to it. If it is 0.26V go to the engine bay and disconnect the steering shaft and rotate it 360 deg to the right, if it is 4.9V then turn it 360 deg to the left. Ask me how I know.

Can you list all locations for the grounds, if possible? And above the diff where? Would I have to drop the diff? And left front on the chassis where?

You can find answers a lot easier with you just start a Google search with C5 Corvette, than your question. The first answers that pop up are usually Corvette forum thread's.
