Function of throttle electronic valve

System composition and function of electronic throttle 1 Accelerator pedal module with accelerator pedal position sensor-used to determine pedal position and transmit pedal position signal to control unit 2 Engine control unit (ECU)- receives pedal position sensor signal and calculates required power according to input voltage signal. According to other torque signals such as sudden acceleration, air conditioning and automatic transmission start, the actual throttle opening is calculated. At the same time, it also monitors the throttle control unit of the throttle system 3-controls the required air intake, adjusts the throttle opening according to the signal provided by the control system, and feeds back the throttle signal. 4 accelerator fault light (EPC light on Volkswagen instrument)-provides the driver with accelerator fault information 5 sensors and actuator sensors: accelerator pedal module with accelerator pedal sensors G79, G 185, G 187, G 188 with accelerator opening sensor, accelerator controller J338, clutch pedal switch F36 and brake pedal switch F47. Brake light switch F 6 actuator: G 186 and G338 with throttle drive device, and K 132 with throttle fault light does not have this name.
