THROTTLE POSITION SENSORS

THROTTLE POSITION SENSOR TECHNICAL DATA

Purpose and Function.

Modern engine management systems require detailed information aboutthrottle position and rate of change. As many vehicle systems are influencedby throttle activity including fuelling requirements, transmission controlstrategy and accessories such as air conditioning accurate data is essen-tial, a simple switch cannot provide this detail.The sensors described below are full range sensors capable of operat-ing in clockwise or anti-clockwise directions and are compact for fitment inrestricted spaces.

ApplicationThese sensors are used in automotiveapplications for measuring the angle ofrotation of the throttle valve. Since thesesensors are directly attached to the throttle-valve housing at the end of the throttle-shaft extension, they are subject to ex-tremely hostile underhood operating con-ditions. To remain fully operational, theymust be resistant to fuels, oils, saline fog,and industrial climate.

Design and functionThe throttle-valve angular-position sensoris a potentiometric sensor with a linearcharacteristic curve. In electronic fuelinjection (EFI) engines it generates avoltage ratio which is proportional to thethrottle valve’s angle of rotation. Thesensor’s rotor is attached to the throttle-valve shaft, and when the throttle valvemoves, the sensor’s special wipers moveover their resistance tracks so that thethrottle’s angular position is transformedinto a voltage ratio. The throttle-valveangular-position sensor’s are not providedwith return springs.

DesignThe position sensor 0 280 122 001 hasone linear characteristic curve.The position sensor 0 280 122 201 hastwo linear characteristic curves.This permits particularly good resolution inthe angular range 0°...23°.
