It is probably reading a range of resistance. Just put a small potentiometer on the sensor wires and start at 0 ohms and turn it up slowly (or start at full resistance and go down if you are scared a short will pop the ECM or TIPM). You'll probably find where the cut-off for low fluid is. It may start of on or off and then go on or off, but it doesn't matter. When varyin' the resistance you'll find the limits. I imagine a 0-1K or 10K pot will do it.
Its a NO-switch between pins C1-8 and C1-9 on the TIPM. Just short the connector at the sensor with a paper clip to test. If that works, then permanently bond the wires together. If that doesn't work, your TIPM could need to be replaced.
thanks for that info joe, i have already trued a jumper wire in the plug with no luck and i am on my 3rd tipm. i might try jumping the wire at the TIPM to rule out a wiring issue?
here are the wires at the sensor plug....

and am i at the right place at the TIPM? section C brown plug?

im not seeing the colors referenced in your pic.
traced the wires all the way back to the TIPM and put the ohm meter to it and got nothing. ran another jumper wire across the sensor plug and still nothing...
I wiggled the wires from the plug and got this.....

the damn wire was corroded at the pin so the sensor was never making contact with the circuit. i could care less if my dash ever beeps at me for washer fluid again. so it is now sealed up with a butt connector and heat shrink. GOOD RIDDANCE!
and just for future reference on my 07 those wires are on the "B" section of the TIPM and not the "C".
thanks for leading me in the right direction tho joe! Anything is better than another TIPM!
Found it. The 2007-2009 TIPM has ports A-L, but they label each of those internally as C1-C10 in the wiring diagrams. Here's why you found it in port B which is wiring diagram C1.
