What should I do if the throttle freezes?

The icing in the throttle is mainly because the exhaust gas enters the intake pipe through the exhaust pipe and the exhaust gas recirculation system. After the vehicle is turned off, the high-temperature exhaust gas entering the intake pipe stays near the throttle. Because the throttle valve is mainly made of aluminum, it conducts heat quickly and cools quickly, so the cold air outside and the high-temperature exhaust gas staying in the throttle valve alternately form water droplets. When the temperature inside and outside the throttle valve is consistent, freezing will occur.

You can blow it with a hot air gun.
