Checked the CPS

Someone said on a forum that you can disconnect the CPS while the car is running and if it stalls then that's how to tell if the CPS is good. Well I disconnected both CPS and the car ran the same. I also disconnected them and started the car and it cranked and still ran the same. It threw up the 71 and 72 faults for the CPS which I wasn't getting before but the symptoms were the same. Is this saying that both CPS are bad. I didn't think the car would run without them.
