    The accelerator pedal on a lot of modern cars is not a cable like older cars, it is a sensor that increases voltage or sends a signal to the computer as to the driver's input. If the computer sees the engine's coolant temperature is too cold or it is "bad" for the engine to accelerate harshly the computer over rides the drivers desire to put the accelerator pedal to the floor board. The computer can also over ride accelerator pedal input to save the transmission or when traction control is exercised.

    Thanks. That's interesting. Could the computer keep the pedal from moving at all ? It will not budge even a quarter inch.
