TPS Sensor Off-Car

Sensors

Throttle Position Sensor (potentiometer)


Checking the Throttle Position Sensor
What type of TPS is this?
Potentionmeter type sensor.

Explain its internal operation and why your voltage changes
T.P.S sensor is a variable resistor which is used for altering electrical potential, as the arms on the carbon resistor pushed the throttle( when the throttle is closed ) the resistance gets higher and the  voltage gets lower. That's why the voltage changes.
