The control unit sends out a five volt reference signal from pin 29 to the tps. It's just a rheostat. It's grounded at pin 3, along with several other components as well as the ecm ground. Since you have injector click by opening and closing the throttle, we can safely assume you have a complete circuit. The third wire goes back to the ecm at terminal eleven. This is the one you want to pay attention to. This is the return voltage from the tps and tells the ecm what position the throttle switch is in. Generally speaking, with the ignition on, and the throttle at rest, the return voltage should be @ one half volt. (point 5 volts). As the throttle is opened, the return voltage should rise to around 4 to 4.5 volts... Verify your results and check back.
Voltage into the sensor is 4.99 (with a non-calibrated voltmeter) measured at the connector. The sensor wire measured at the connector shows 4.5v with it disconnected. Should it measure anything at all at this point? The sensor wasn’t connected.
