Error 3 is related to the speed sensor or motor as others have already stated.  Sometimes this error can be something simple.  For example, as the motor shock mounts wear over time (or if the end user doesn't balance the rotor properly) the motor takes on a lot of vibration.  Sometimes its bad enough to shake the motor connector loose.  I just fixed one like this recently.  So always check the easier issues first like the motor connector and the speed sensor connector to see if they are seated properly.
