What will happen if the car throttle fails?

A broken throttle will lead to unstable idle speed of the engine, difficult cold start of the engine, poor acceleration performance, black smoke from the exhaust pipe and increased fuel consumption! At the same time, the engine fault light will light up. First, there is something wrong with the throttle of the car. You can use the computer to check the engine system for fault codes and see if the data flow of the accelerator pedal is normal. If the data flow is abnormal, first check whether the throttle has too much carbon deposit and whether the throttle is stuck. Whether the throttle itself is damaged, and whether the line is short-circuited or open-circuited. Second, the throttle valve is a controllable valve that controls air to enter the engine. After the air enters the intake pipe, it will be mixed with gasoline to form a combustible mixture, which will be successfully formed after combustion. Known as the throat of an automobile engine, it is connected with an air filter above and an engine cylinder below. There are two kinds of throttles: traditional cable throttle and electronic throttle. The traditional engine throttle control mechanism works by pulling a cable or pull rod. One end of the cable or pull rod is connected with the accelerator pedal, and the other end is connected with the accelerator linkage plate. Electronic throttle mainly uses throttle position sensor to control the opening of throttle, and adjusts the air intake according to the energy required by the engine.
