2.2 Lower body (air system)—description and function of accessories installed on the lower body. ·throttle valve position sensor sensor) ·PCV recirculation pipe output signal and throttle valve opening ange.
·Sensor component is consisted of a potentiometer. The slipping ruler of potentiometer is driven directly by accelerator pedal which is proportional with throttle valve opening. ·the potentiometer is inserted into plastic case with two baffles on the bracket. There are two holes in the bracket for installing the potentiometer on throttle valve. · there is spline on the shaft. The spine provides data about throttle position. The data is used to confirm idle operation condition (accelerator pedal released), full load (accelerator pedal depressed) and accelerating or Fig.139 temperature sensor and principle water Air Connecting chart Fig. 140 throttle valve position sensor and operation chart Ground Signal output Power Throttle valve opening (angle)
