Is there anything wrong with BYD g3 09? Idle speed is too high.

This idle speed is on the high side,

Generally, it is because our throttle is too dirty, stuck, can't be turned off properly and needs cleaning.

And the throttle may be cleaned without self-learning or matching. This situation needs to be matched by a computer.

And check whether the idle motor is damaged, that is, check whether the water temperature sensor is damaged and whether the signal of the water temperature sensor is bad.

Now we need to check whether our positive crankcase ventilation valve is damaged or not.

Check whether the pressure in the fuel system is too high, and check whether the oil pressure regulator and injector inject oil normally.

Need to check

I hope I can help you. If there is something wrong with your car, ask the car mechanic. 4S shop professional technician, 10 minutes to solve.
