The ECU in your car is very clever. It continually adjusts the fuel/air ratio according to numerous variables to give the best output. The throttle position is just one of these many variables it monitors. For example, when you lightly press the pedal it knows you are after more economical output whereas if you push the pedal to the floor it knows your after the best power output.
