Is there a relearn to a tps after replacing?

Make sure your tps doesn't need an adjustment. If the slots that the screws go through are elongated then it can be adjusted. Alex

when you removed the old TPS,you should have seen/felt a little resistance because the TPS is spring loaded and has to be put back on in the same way as the old one came off.The 2 notches/tabs are in the TPS for a reason. You can probably drive it and floor it after getting up to a speed and it won't open the throttle to go any faster because the tabs are not lined up correctly to open the throttle. it's either that or not a good quality part.take it back off,put it on at an angle to put tension on it then turn it to line up the screw holes,put the screws in and tighten it back down,see what happens.
