Need Test Procedure for 2003 Sedona Throttle Position Sensor (4 pin)

Seems all references to TPS testing is for 3 pin sensors. Maybe its the same for a 4 pin sensor leaving one pin out of the mix???
Any help with testing a 4 pin TPS for a 2003 Sedona 3.5L would be greatly appreciated.
Thanks.

From the autozone site

This has instructions:

There is not a pin out diagram, but pin number one is ground. So the end connection that has no resistance should be ground.
The plug from the wire loom has a removable backshell. I was able to back probe it with paper clips. Then I noticed my scanner (which I had only used as a code reader before) would show live data, and the TPS was in the list.

Thanks Sedonarunscrappy,
Researched a bunch more and compared 3 pin test to 4 pin tests. I found 4 pin test for Toyota. (dare I mention that car in this forum)
Awesome scanner stuff. Shopping for one myself.
Testing voltage for signal wire, and power wire, same for 3 pin and 4 pin. 4 pin sensor includes an Idle Switch to test and then possibly TPS assembly adjustment.
Problem for me right now is finding/verifying voltage specs for 2003 Sedona. Toyota specs may be same but not sure and will not proceed without verifying specs for 2003 Sedona.
Brings me to my other post about finding a repair manual. Shying away from digital downloads. Not likeing reviews. Old school manuals are my preference. A bit expensive.
Thanks for your response. Have fun with scanner.
