What is the voltage of Chery a5 throttle potentiometer 2?

(1) The voltage of the accelerator potentiometer 2 of Chery a5 is 5V.

(2) Cause: The throttle position sensor is a sliding resistor, and the equivalent circuit is two resistors in series. A fixed voltage (5V) is applied to both ends of the two resistors, and a signal is obtained at the connection point of the two resistors. Changing the throttle position is equivalent to changing the resistance of two resistors, which leads to the change of voltage drop at the connection point of two resistors.

Working principle of throttle potentiometer:

(1) consists of two contactless linear potentiometer sensors, and the ECU provides the same reference voltage.

(2) When the throttle position changes, the resistance of the potentiometer changes linearly, thus generating a corresponding voltage signal to be input to the ECU, which reflects the throttle opening and change rate.
