C0051 is a steering wheel position / steering angle sensor fault. After a battery disconnect, alignment, or clockspring service it often just needs a steering angle sensor recalibration with a capable scan tool. If recalibration fails, the sensor (in the steering column clockspring assembly) is the replacement. Always recalibrate after replacing.
