Default IAT TESTING

I have a 97 civic with an LS swap I am getting a code P0112. So my question is what readings should I be getting to the plug ( voltage and resitance) just to make sure it's not a wiring issue.

This are my results on the IAT connector WITH THE KEY IN THE ON POSITION.
One lead on the positive post of the batter
Green / Black wire = -13.70Mohms and -12.28V
Red / white = -13.17Mohms and -7.30V
One lead on the negative post of the battery
Green / Black= 33.7 ohms (not mega) and 0.01V
Red / white = open and 4.99V

Any one care to share their input on these results???

Ohm testing sensor - unplug connector and measure resistance across the 2 sensor terminals.

I have 3 different sensors and they all read the same thing... you think they are all bad?

You are either doing the resistance test incorrectly or all 3 sensors are bad. Post clear pictures showing how you are resistance testing the sensor. Also post a picture of your multimeter.
