THROTTLE BODY POSITION
The sensor of the throttle position (1) is located in the
centre of the throttle body.
This sensor is a potentiometer with a resistance which
varies according to the opening angle of the accelera-
tor.
The sensor is supplied by the ECU at a stabilised vol-
tage of 5V and supplies an output voltage proportiona-
te to the throttle angle.
The basic injection time of the fuel (volume) is deter-
mined according to the output voltage of this sensor.
The voltage increases when the accelerator opening is
increased.
