Default I Need help!! Lol

I have an 04 mitsubishi endeavor xls 3.8L AWD. When I start it, it idles fine. When I press on the gas pedal nothing. I mean barly anything, slight rpm raise. It doesn't do anything. I put the code reader on it. It comes up with P2100. Throttle body actuator open circuit. So then I Google it and found a checklist of things to try and things to test. Im at step 4 and it says to test the continuity between 2 pins on the B-109 plug on the harness side.
so my question is A. Does anyone have an idea why my vehical is doing this? B. Does anyone know why im getting a P 2100 code. C. Where the heck is the B-109 plug at the ecu. Any help would greatly be appreciated. Thanks again
