Throttle Angle Sensor

The throttle angle sensor is a 3-wire potentiometer that is connected to the throttle valve shaft. As the throttle angle changes, the throttle angle sensor varies the voltage signal which is monitored by the control unit. Sensor voltage will range from about one volt at closed throttle, up to about 5 volts at wide open throttle.
