    How the throttle position sensor for two-wheelers works


     

    The throttle position sensor measures the angle of the throttle valve in gasoline engines. The signal of the throttle position sensor is used to more precisely calculate the fuel injection quantity.

    Bosch's throttle position sensor is a potentiometer with a linear characteristic curve. The rotor arm, which is connected to the throttle valve shaft, moves its wipers along the resistance tracks. This translates the angle of the throttle valve into a proportional voltage ratio.

    Technical characteristics:

    • Angle sensor with linear functional characteristic (potentiometer)
    • Ratio metric signal with diagnostic limits
    • Measureable electrical angle: 0° – 96°
    • Clockwise and counterclockwise rotation possible
    • Two-hole mounting system
    • 8-mm throttle shaft interface with D-shaped cross-section
    • Temperature range: -40 °C to +130 °C
     
     
     
  • Customer benefits

    Responsive – precise – flexible


     

    Throttle position sensors are built directly onto the throttle housing, along with an extended throttle valve shaft. To function in such extreme situations, the sensors are resistant to substances such as fuel, oil, salt spray, and industrial conditions.

    • Better calculation of the filling quantity
    • Improved fulfillment of emission requirements
    • More dynamic engine response to changes in driving behavior
    • Flexible assembly for different applications
    • Packaging advantage due to small size
