A potentiometer a three wire variable resistor is used in which type of sensor ?

A potentiometer a three wire variable resistor is used in Throttle position (TPS) Sensor.

Explanation:

A potentiometer is a three-terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider. In case only two terminals are used, one end and the wiper, it acts as a variable resistor or rheostat.

A throttle position sensor (TPS) is a sensor which is  used to monitor the air intake by  an engine. This sensor is usually located on the shaft or the butterfly spindle because it can be directly  be used to use the position of the THROTTLE

The Throttle Position Sensor (TPS)  is a part of Fuel Management system of a vechile.The proper function of Throttle Position Sensor (TPS) ensures that the right amount of fuel and air is delivered to the vechile engine.
