Even though you think your test lights are correct, the only real way to find out is to do the test with the voltmeters. Also, check the resistance according to the FSM. At idle, you should have about 1,000 ohms. At wide open throttle (TPS fully extended), you should have about 5,000 ohms. If my memory is right, take the plug off the TPS and have the plug facing you so that it looks like an upside down face (without the smile). Check resistance at the top prong and bottom right prong.
