Tianyu Sx4 throttle normal voltage

According to different working conditions, the opening is also different. The signal voltage output by the electronic throttle is between 0.5 and 4.5 volts, and the voltage less than 0.5 volts and greater than 4.5 volts is used to identify the short circuit and open circuit of the line.

Just after washing the throttle, how do you know that the increase in fuel consumption must be caused by the throttle? Your mechanical throttle should be adjustable. It is recommended to adjust the output voltage to about 0.5V at idle speed. At the same time, check whether the air filter and the gasoline filter are too dirty, check the combustion of the spark plug, and clean the fuel injector if necessary.

The throttle cannot be completely closed, so it is normal for you to see a gap in the middle valve plate.
