What kinds of throttle position sensors are there?

The types and descriptions of throttle position sensors are as follows: 1. Hall throttle position sensor: It is mainly composed of Hall element and magnet, in which the magnet is installed on the throttle shaft and can rotate around the Hall element. When the throttle opening changes, the magnet rotates with it, thus changing the relative position with the Hall element, and the Hall IC is surrounded by the yoke. Hall IC converts the change of magnetic flux into electrical signal, which is output to ECM in the form of throttle position signal. 2. Double variable resistance throttle position sensor: Generally, the two sensors in the double variable resistance throttle position sensor are installed in combination, and when one sensor fails, it can be identified in time, which increases the reliability of the system. Judging from the relationship between the output signals of the two sensors, there are two types: anti-phase type and in-phase type. In-phase formulas can be divided into two types: linear changes with the same slope and linear changes with different slopes. 3. Sliding resistance throttle position sensor: also known as linear output throttle position sensor, variable resistance throttle position sensor and potentiometer throttle position sensor. At present, the dual variable resistance throttle position sensor is widely used in automobiles.
