Why clean the throttle and set the throttle initialization?
Hello, first of all, let me introduce the function of throttle, which is the sensor that controls the main data of engine and automatic transmission. During our long-term use, the air at the air inlet and the exhaust gas from the cylinder block will stick to the throttle valve, gradually increasing the opening of the throttle valve. At the same time, the electronic control unit will remember and store the changing position of the throttle. If it is not cleaned for a long time, the idle speed of the engine will be high and unstable, the fuel quantity will increase, and the shift of the transmission gear will not be synchronized with the engine speed.
After cleaning the throttle, the ECU will remember the throttle position before cleaning. After cleaning the throttle, the air intake gap becomes larger at idle speed, and the engine speed increases at idle speed (1200-2000). Therefore, it is necessary to manually match the engine electronic control unit or use a computer detector. The electronic control unit controls the throttle opening to reach the appropriate air intake, and the idle speed is (750-800 normal).
