How often does the car throttle need to be changed?

If the accelerator of a car is broken, it will be replaced. The manufacturer did not specify the replacement cycle of the accelerator. Throttle valve, also known as "throttle valve" and "throttle valve". Refers to the control device that controls the engine power. The traditional cable accelerator works through a cable or a pull rod, one end of which is connected with the accelerator pedal and the other end is connected with the accelerator linkage plate. Electronic throttle uses wires instead of cables or pull rods, and a micro motor is installed at the end of the throttle to drive the throttle opening. There is no response when stepping on the accelerator, indicating that the power of the car is abnormal, and the engine power is coordinated by the intake system, ignition system and oil system. If any component is abnormal, it may lead to the decrease of engine power, resulting in slow response when stepping on the accelerator, body shaking and exhaust smoke. When stepping on the throttle, the cable will drive the throttle, and there is a position sensor on the throttle. The control unit knows the throttle opening according to the signal of the throttle position sensor, then calculates the corresponding signal voltage, and finally calculates the fuel injection quantity of the vehicle according to the single pressure of this signal. Therefore, if the throttle position sensor is too dirty or the voltage is unbalanced, the electronic throttle will fail and the throttle will not go up at the bottom speed. In addition, if the air intake system leaks or is blocked, when the car refuels, the power will drop, the speed will not go up, and the body will shake. Also, if inferior gasoline is added, it will directly affect the engine power, which will easily lead to the engine stalling and accelerating, and it will be impossible to speed up. 5. The performance degradation of spark plug will also lead to acceleration weakness and acceleration jitter.
