The sensor,actually it's a switch, on the end of the MC is for the CC. If you have the trac assist there's a pressure sensor on the brake booster. Your vehicle doesn't support the Advance Trac. The only way to solve your issue is to get it scanned with a different tool. The Rotunda tool is the factory scan tool for Ford. The only thing I can suggest is to clean up the tone rings and take the connectors off the ABS module and spray them with GOOD electrical contact cleaner and apply dielectric grease and plug them back in. If you still have problems you'll need to get it scanned to see what is going on.
