How many wires does the throttle DC motor have? How many volts is the voltage?

Generally, an electric throttle has six wires, two are motors driving the throttle, and four are used to detect the throttle position. Two of these four wires are power sources, and the voltage is 5V. The two wires have different voltages according to the throttle opening, but the two wires add up to 5V.

Electronic throttle is an important control part of automobile engine. It consists of engine, speed sensor, throttle and so on. The electronic throttle control system can accurately control the throttle opening.

The basic structure of the electronic throttle system consists of the following parts: 1, engine 2, speed sensor 3, throttle position sensor 4, throttle actuator 5, throttle 6, accelerator pedal position sensor 7,? Speed sensor? 8. Transmission 9, accelerator pedal 10, throttle electronic control unit (ECU).

System composition:

1. Accelerator pedal module with accelerator pedal position sensor-used to determine the pedal position and transmit the pedal position signal to the control unit.

2. Engine Control Unit (ECU)- receives the signal from the pedal position sensor and calculates the required power according to the input voltage signal. According to other torque signals such as sudden acceleration, air conditioning and automatic transmission start, the actual throttle opening is calculated. It also monitors the throttle system.

3. Throttle control unit-controls the required air intake, adjusts the throttle opening according to the signal provided by the control system, and feeds back the throttle signal.
