The throttle position sensor is integrated with the throttle manipulator and attached to the throttle shaft. The throttle manipulator passes through the idle switch, and the throttle position potentiometer transmits the current throttle position signal to the engine ECU, and the ECU controls the throttler positioner according to the signal.
In the car pull line, one is the engine, and the accelerator pedal pulls the engine throttle line to control the opening of the throttle to control the engine speed. The other is the oil valve line of the automatic transmission. The accelerator pedal pulls the engine throttle line to control the opening degree of the throttle valve, thereby synchronously pulling the automatic transmission oil valve line to control the opening degree of the oil valve inside the transmission, and controlling the automatic pressure. The amount of oil that the shifting oil enters into the transmission manifold, thereby synchronously controlling the upshift or downshift of the automatic transmission based on the speed of the engine.
As we all know, the throttle is in the pipeline of the intake air, adding a set of butterfly valves, using the different rotation angles of the valve plates and different openings to control the intake air volume and further Auto Brake Hose the power of the engine. Nowadays, the vehicle adopts electronic throttle design, which can be precisely controlled by the engine control module to increase output and reduce fuel consumption. The traditional throttle is mechanically driven by the throttle cable. However, for the integrity of the entire vehicle control, many new models have adopted electronically controlled throttle.
