I’m now checking the TPS voltages with 2 different multimeters and refrencing a NA Sr20 from a G20 just to be sure.  
On my S14 Sr20DET I’m probing the following wires:

A-blk -gnd  
B-w - from tps( .4v closed 5v open)  
C-lg/r - from ecu (5v)

My results:  
.01Vclosed and .08 open  
.2V from ecu and 2 when running?

refernced sr20DE from G20  
.4v and 4.9 open  
5v

What the heck is going on, is the SR20DET using different voltages?

no a tps usually ranges from what you said up there, all tps use the same principle with a 5v ref. sounds like you have a crapped out tps
