DeVille V8-4.9L VIN B (1995)
Throttle Position Sensor: Electrical Specifications
Voltage Versus Throttle Position Chart
The PCM supplies a 5 volt reference signal and a ground to the TP sensor, and the sensor in turn sends a voltage signal representing throttle position
back to the PCM.
A closed throttle angle will result in a voltage signal near 0 and wide open throttle will produce a signal near 5 volts.
