It did. I don't think you are understanding me. I have codes and reason and can clear them.....BUT they come back DIFFERENT faults to before or only i sensor with a fault or 2 or 3 or all 4 ect. If it was the sensors, the faults wouldn't change each time and all the sensors with faults would all have faults each time. Sorry if i wasn't being clear or if im still not.

sounds to me like the ECU is playing up, dodgy earth, and/or connections. or maybe an internal fault.
(Can't see why doing the bypass would fix it or even improve things.)
Do ensure the earth(s) is/are clean and properly connected, ditto the batt terminals and that it itself is up to snuff.
Anyway, best of luck with it all!
