How to judge that the throttle is broken?

1. Engine idle speed is unstable, high idle speed does not drop, and engine start is difficult, especially cold start;

2. The engine is unstable or not idling;

3. The engine is difficult to start;

4. Insufficient engine power, poor acceleration performance and unstable operation;

5. The automobile exhaust pipe emits black smoke, which increases fuel consumption;

6. If the throttle is broken, the EPC light on the instrument will light up, indicating that there is something wrong with the electronic throttle control system.

How to check whether the throttle valve is damaged:

In automobile repair, it is more troublesome to directly adopt the method of disassembly and inspection. The most accurate method is to check the throttle with a scan tool, observe the data flow and find out the problem. If the inspection shows that the throttle opening is large, it needs to be cleaned. If it is determined that the throttle fault is permanent, it must be replaced. Because the throttle cannot be disassembled for maintenance, only the assembly can be replaced.

In addition, it should be noted that proper cleaning of the throttle can ensure the normal operation of the engine, but the cleaning must be controlled. Excessive cleaning can easily lead to premature scrapping of the throttle. Because frequent cleaning will gradually clean off the special coating in the throttle cavity, once the coating falls off, it is easy to cause greasy adhesion, and the final result may make it scrapped.
