More insight on Nissan 6 wire throttle position sensor How it works in correlation with the accelerator pedal

Nissan/Suzuki 6 wire tps System I'm still slightly confused about I watched danners videos over and over

I get the 5 V Reference wire and the resistor that sends the power to the other side when un plugged (signal wires)

When it is plugged back in the 5 V disappears on the signal and it goes to slightly under 1 Volt throttle plate closed

1 of 2 things I'm not understanding is when You depress accelerator pedal I understand it sends voltage signal to the ECM and then the ECM sends it to the TPS to actuate the butterfly , but When does the Signal wire 1 start receiving voltage Or does it not ? Too actually literally move the butterfly valve and is it only 5 V that moves it or 12?
as the accelerator pedal is depressed all the way up to under 5 v wot..

Also number 2)
What is throttle motor pins 5 and 6 +/- for I noticed these 2 wires are heavier gauge it seems like power would come from the ECM To these pins and reverse the polarity to open or close the motor is that correct in my thinking or not

Please clear this up for me Thanks Paul for your videos I have learned so much already I am a diesel technician so in our world There is no throttle bodies everything is controlled by the injectors

OK so the signal wires are literally just inputs to tell that ECM its position and that is it's only job?
What I want to know is what literally opens up the throttle butterfly valve is it 5 and 6 pin? In my picture above And Would I expect to see 12 V on that circuit coming from the ECM To literally control the tps motor open and close?

Keep in mind my throttle body is not cable controlled it is all electric with 6 wires

The first thing is for safety reasons as a fail safe on any drive by wire gasoline engine the TPS is actually two TPS sensors built into one unit. TPS1 works in the opposite direction to TPS2 .
Closed Throttle TPS1 will read close to 0V on its signal wire but TPS2 will read close to 5v on its signal wire.
Fully Open Throttle TPS1 will read close to 5V on its signal wire but TPS2 will read close to 0v on its signal wire.

The 5v you see on the signal wires when disconnected from the throttlebody is not a real voltage but ghost bias voltage that the ecu uses to test circuit integrity. This ghost bias voltage on the signal wires has to pass through a very high resistance before it reaches the plug on the throttle body, because the tps sensors are voltage deviders a much lower resistance (typically 3.,600 ohms max) the ghost bias voltage is over written (up or down) by the the voltage output from the tps.

Thanks so much that helps a lot I guess I was over thinking it !!!!! Totally makes since!
