Signal failure of Fukang 998 throttle potentiometer

Throttle potentiometer is a throttle position sensor.

How is the headache? Check whether the 5V reference voltage of the plug is good first, and then check whether the pins and pins of the plug are complete, corrosion-free and in good contact.

Everything has been checked, and there is no problem. Mainly the throttle position sensor. Of course, it is safer to check the connection with the computer before changing.

I wish you success!
