The new Chang 'an Star 7 electronic throttle sometimes doesn't respond.

When you are driving, you have to refuel at idle speed. You didn't respond when you stepped on the accelerator pedal. When reading the data, you find that the throttle opening is negative, and it does not increase with stepping on the throttle, but decreases, indicating that there is something wrong with the throttle or the engine computer. Well, if you are sure that the throttle plug and wiring are all right, then change the throttle, otherwise it is a computer board problem. Change the throttle first, don't twist it. By comparing the old and new throttle data, we can know that the throttle should be changed.
