Suburban 3/4 Ton 4WD V8-305 5.0L (1986)
Throttle Position Sensor: Description and Operation
The TPS is mounted in the carburetor body and is moved by the accelerator pump linkage. When the throttle blades are closed, the TPS provides a low
voltage (under 1 volt). This voltage signal will increase to up to 5 volts as the throttle blades are opened to wide open throttle. These voltage signals
provide an indication of throttle position to the ECM.
