 Anyone...?

If the "servo" in the throttle body is just a brushed motor (per the mention at the Infineon site), then controlling the position with pot might be fairly easy. Does the throttle plate have any position feedback?

 Thanks for your help. Yes the plate has two position sensors. Both are 5V, but their range is reversed, at a given position the feedback from the two position sensors has to "match". This is the principle. The accelerator pedal features 2 potentionmeters.

 Thanks for the advice but i am far from a little child. Nothing is going to be in the engine bay anyway. The throttle pedal will remain where it is meant to be, under my right foot, and the throttle body where it was meant to "live" too, in the hood. The controller is the whole thing. I would apreciate it if you could help with this project.

 It's PWM driven btw

k3nshin, Please don't do anything to your car's electronic throttle. If you make a mistake and you have an accident that hurts or kills someone, you will be in a big trouble.

 I have a spare accelerator pedal and throttle body to test, so extensive testing will be done first before trying it on my car. I am converting to a standalone ECU and i have to find a solution for this... from a short search, i found another 2-3 threads in the forum regarding the exact same subject, but no information that would help unortunately.
 This is what i am looking into :

Any ideas as to what kind of motor it is?

 What else would we need to know apart from that it is a 12V servo motor?

Hello guys!
I want to control the 12 V servo motor that is responsible for the electric throttle in my car.
In fact, I want to use a potentiometer in order to turn the servo motor of the car.
Is it possible for an arduino to control such a servo? Do I need a motor control shield? (I plan to supply the servo with 12 V from the vehicle batteries)
Finally, do I need to connect arduino ground pin with the negative of the car's batteries?
Thank you in advance.
