Is the plug of the accelerator position sensor of Fukang car two-wire or three-wire?

The plug of the throttle position sensor of this car is three-wire.

This sensor consists of a linear potentiometer and an idle switch, in which two pins are located at both ends of the resistor, which are used as the power supply terminal and the grounding terminal respectively, providing 5V voltage from the engine ECU, and the third pin is connected to the sliding contact. This sensor can be tested by ohmmeter or multimeter, changing the gap between the throttle lever and the stop screw, and measuring the resistance or voltage between the ground wire and all other wires in turn, which should meet the specified value.
