Default STR High Idle and TPS Range

So I removed my throttle body and removed the TPS from it to clean inside as shown in a thread that I can't find at the moment on this forum.

After reinstalling I checked with a scanner to make sure it works before starting the engine.

The engine started at about 1500 rps and wouldn't go lower than 900 even after warmup.

Also when decreasing throttle the engine would speed up after it slowed down and than slow down again. TPS% were hitting 0% on my scanner.

Does that mean I have to recalibrate the TPS somehow so it doesn't hit 0% when no throttle is applied?

Codes in the system are P0507 and P0121.
