okay so i recently made a thread about changing my knock sensor and well to get the that i had to take off the whole air intake manifold and now that i got it all put back together i got a p0223 and other related codes and i thought it was just me not plugging something back up but everything is in the right place, is theres something i have to replace or do i just need to do a relearn and is so how do i do that. i will say that my thumb did the little throttle flap,, i dont really know what that is called

 

Looks like a TPS code. You can do a search and find the reset/relearn procedure.

 

Throttle closed position,
Idle air volume

Also posted in the FSM, section EC at the front under basic service procedures.

 

However since it was fine before you unplugged stuff I'm betting you accidentally bent a pin in the throttle harness.
