did you clear the codes after you did the work?

clearing the codes would be what you need to do, or after a certain miles or a drive cycle it will shut off itself, but why you have a new code after changing some sensors is odd, unless you left something disconnected

yea after i did the work i cleared the codes hoping that it would stay off ,but just a short time later it came back on and then that's when i checked it again and it gave me the other code and am sure i didn't leave anything disconnected

check wiring continuity back to the ECM. if that checks out good, I would seriously think it's the ECU which is rather a rare failure
