TPS (throttle position Sensor) is a variable potentiometer! Is is connected to the throttle shaft on the throttle body. The ECM/PCM (computer) uses the voltage from the TPS to determine fuel delivery based on the angle of the throttle shaft or valve (driver demand)

A loose or broken TPS can cause an unstable idle or intermittent bursts of fuel from the fuel injectors, because the ECM/PCM is fooled into thinking the throttle is moving.
