I have a 2006 chrysler 300 3.5L V6 my throttle position sensor went bad so I changed it out I had to change the whole throttle body out because the TPS is connected to it is it true that you have to reprogram it because after I put the new one on it still acting the same way as the old one did.

Do you
have the same problem?

What was the code that appeared that you changed the tps? Scan for codes and check fuel pressure first. And no you don't need to reprogram after replacing tps

The codes I got were P2173, P0123, P0222, P2111 so you need a scan tool you can't do it yourself manually.

Nope it has to be a pro model or a dealer one. This could have been caused by two things, one alrage vacuumleak, like ahose off or similar and/or alot of carbon buildup on the throttle plate and not letting it close all the way. Normally cleaned with choke cleaner to get rid of that. You could also have a vacuum leak due to hoses having holes in them

Before I changed out the throttlebody/TPS I cleaned it out with throttle body cleaner it didn't work, then I got fuel injector cleaner and sprayed it on all the vacuum lines and around the intake manifold and there was no leakes.
