I have a persistent C-2202 Developing Motor M3 Speed abnormality. I replaced the entire developer unit because it felt like it was binding and that remedied the issue for a couple thousand copies. The error returned and I replaced M3 and the error persists. I cleaned the old developer unit and put new developer in it and the error persists. Any help would be appreciated.

Are you watching the motor with rear cover off? What happen if you run it from I/O test mode.
It works with a feedback system from the hall effect sensors in the the motor. If that motor runs up to speed and still errors out the PCRB is your next move.
Does it feel stiff if you rotate the motor by hand?
Check the 24V on the motor connector.
Look for damage to the PCRB and harness also if one wire is grounded with a screw.

Can't find ICP for M3 in ICP list.
