Cherokee 4WD V6-173 2.8L VIN W 2-bbl (1985)
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.
