Throttle Position Sensor: Description and Operation
The TPS is mounted on the throttle body and senses the angle of the throttle plate opening. The sensor produces a voltage signal which increases and
decreases according to throttle position. The SMEC uses these voltage signals to tailor air/fuel mixtures for varying conditions such as idle, wide open
throttle, acceleration and deceleration.
