Throttle Position Sensor
Sensors of this type are used in motor vehicles to register the angle of rotation on the throttle valve and the rate of change. The sensor is used to generate a secondary load signal, which amongst other things, is used as auxiliary information for dynamic functions, as well as for recognition of operating range, from idle, through part, to wide open throttle position, and as a limp home or emergency signal in case of a failure of the primary load sensor (air mass sensor).
They are exposed to extreme operating conditions, being attached directly to the throttle valve housing by means of an extended throttle valve shaft in the engine compartment. To maintain reliable operation under such conditions, the sensors are resistant to fuels, oils, saline fog and an industrial atmosphere.
