6-wire electronic throttle pin definition

Different manufacturers of electronic control system have different definitions of six wires of electronic throttle, but they are generally 1 power supply, 2 while the iron is hot, 3 signal wires of motor position sensor, 4 power wires of sensor are 5 volts, 5 signal wires of throttle position sensor and 6 ground wires. 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 electronic throttle system consists of the following parts: engine, speed sensor, throttle position sensor, throttle actuator, throttle, accelerator pedal position sensor, speed sensor, transmission, accelerator pedal and throttle electronic control unit (ECU). The impact of electronic throttle failure on the engine is as follows: 1, the engine idle speed is unstable, the idle speed continues to drop, and it is difficult to start the engine, which is the cold start difficulty; 2, the engine idle speed instability or no idle speed; 3. The engine is difficult to start; 4. The engine has insufficient power, poor acceleration performance and unstable operation.
