What's wrong with Chery Yun Qi's fault light?

Generally, the engine control unit has a learning function, and the control unit with dirty throttle is also learning bit by bit. When cleaning the throttle, the control unit can't adapt at once, so your car has a fault. Generally, it can be solved by clearing the learning value of the control unit with a diagnostic instrument, but the engine control unit of some models does not have this function, and the learning value can also be cleared by disconnecting the negative battery and powering off the control unit.

I hope the above answers are helpful to you. Thank you.
