i was driving around normal today and got this code P2100 Throttle Actuator Control Motor Circuit/Open

made no changes to my car in the last couple weeks. i EM is ecutek and i run a fp green/meth setup.

anyone have any idea about this code? it goes it the dealership in the morning but its driving me crazy!!!

help???!!

noone?

car is at the dealer now, will post results once something is found.

Saw similar codes when I put a turbo on my last vehicle.
Like you found it relates to the throttle control circuit. There is a comparator between the TPS ( still has one even tho it's DBW ), TB position, and MAP. If one or more of them go out of tolerance ( ours was 10% ) it throws the code. Bad part on my old truck was it went to "limp mode" which shuts down the throttle control but keeps the engine idling so the PS and brakes still work until you pull to the side and cycle the key.
Anyway my problem was trying to trick the stock MAP into reading positive pressure ( n/a MAP's don't like this ).
Guessing they will find one of the above mentioned parts defective else maybe the upgraded turbo and ECU are doing something weird ( overboost, underboost, etc ).

when i took it to the dealer, it came up as code 2096. something with the o2 sensor.
