Default P1633 code

Not sure if this has been psoted but if so I apologize for restarting. I have been getting the ABS?STC as well as check engine light and service light coming on every now and then. I scanned it with a ACTRON OBD II and it pulled up this code P1633 Manufacture Control Auxiliary input/ output. Does anyone know what this may mean?

It is most likely a speed sensor code coming from a bad ABS module.
Not 100% sure don't have my p code list in front of me.

A bad ABS module will send a code to the ECM when the module goes bad.

How would I go about fixing that? Does that by any chance have to do with a ABS Mdoule? I am having similiar problems that was listed in one of the forums concering the CEL.

Yes a bad ABS module will set the code in the engine computer.

Is there one sensor or is there a sensor at each wheel? I have the same code on my 2000.

Thank you
