ML430-1999-Acelarator issue

Hello I replaced my pedal position sensor and did the reset procedure multiple times. Unfortunately the accelerator is not responding. every time I either use the pedal or the TPS under the hood the engine still does not rev up. It just starts to run a little rough.

Could it be the throttle body ? My question is what does the TPS talk to or connect to? That then communicates with the throttle body.
Any help would be appreciated.
