Circuit Descriptions Of The GM TPS Sensor Like the majority of throttle position sensors on modern fuel injected cars and trucks nowadays the GM TPS is a three wire sensor. As the throttle blade is opened TPS sensor 1 voltage sweeps toward 5V reference and TPS sensor 2 voltage sweeps toward low reference. Stick the pin in the center wire of the throttle position sensor plug. These opposing signals are used by the PCM to monitor and make one throttle angle PID available.
