Talking NEW TPS caused havoc !

I thought maybe by getting a NEW TPS sensor may improve idling - BIG mistake again lol .... BABABUI my TB ,, it had actually been running decent much better than before .. NOW i got the dreaded code P0122 throttle /pedal .....circuit low which is with the OLD one back on ,, got rid of the NEW one ( got more codes with that one)
whatever damage has been done .. getting NOW DSC not working , engine fault ,, limp mode eally..

read check power on fuse F18 .. no power at all .. I just ordered a used TB from ebay which I believe it should be plug and play IF no damage was done to the ECM ..

questions is there a proper way to install a TPS sensor and how to check the leads - I have electrical wiring OY positive , GB negative OTHER two wires INPUTS .?

There is a detailed how to calibrate the TPS posted in the S type stickies.
although I’ve never had to , it states It is necessary after battery disconnection.
I wonder if this could help.
