I'm one who purchased a Borg Warner CPS when I got a Code indicating the it was bad, because it was available .... today. My car quit, dead, everytime the engine hit 4000 rpms with it. So, I cleaned the original Bosch part, cleaned the plug, reinstalled it and to this day it's working perfectly. Most of the time the CPS is fine, it's a dirty or poor connection at the plug. Clean it, snap the connector on and off multiple times, use some dielectric grease and you'll be golden more often than not.
