Abstract
A throttle valve position sensor in which a non-contacting, magnetic field sensor is coupled to or integral with a gear wheel of a geared throttle valve control. The sensor provides a more durable sensor. Sensor circuitry can be provided on the lid of the control, along with control motor electrical connections, so that the sensor and control motor can be connected by simple joining in a single operation. The throttle control valve is intended for internal combustion engines for motor vehicles.
