Under what circumstances should the throttle assembly be replaced?

Under what circumstances should the throttle assembly be replaced? If there is something wrong with your car, the mechanic may tell you that you need to change the throttle of your car. So, under what circumstances do you need to change the throttle? Generally speaking, the following are some common causes of throttle damage: 1. If the throttle is damaged, the EPC light on the dashboard will light up, indicating that there is something wrong with the electronic throttle control system. 2. The cold car is difficult to start, the idle speed is unstable, and the black smoke may also be caused by the damage of the throttle. 3. The vehicle cannot be started, and the diagnostic equipment detects that the engine system reports that the throttle valve is damaged or the sensor is unreliable. 4. Problems such as sliding and flameout occur during driving. 5. Measure the throttle opening with diagnostic equipment to see if it is within the normal range. If the throttle angle is still too large after cleaning the throttle, the throttle needs to be replaced. 6. The basic setting of throttle valve was unsuccessful. After the wiring problems, battery problems, engine adjustment unit and other problems are eliminated, the throttle valve needs to be replaced. The above phenomenon is the throttle damage that vehicles often encounter. Of course, there are other external factors that may also affect the throttle damage. In this case, it is best to drive the vehicle to a 4S shop or repair shop for inspection to determine the cause of the failure.
