2.36 what ? The number doesn't make any sense, as you can see from the table the resistance is anywhere from 290 kOhms to 400 Ohms. If you indeed measure 2.36 Ohms with a cold engine the sensor is defective.

 

Think that is the volts reading.

 

sorry for the confusion I was measuring in kohms so (2360ohms). the bigger issue is that the live data on my scanner stays locked at 145°F no matter what I do. I unplugged the sensor (which should show -40) and I jumped the pins with a paperclip (which should show 280+), and the scanner didn't move a single degree either way. I already checked continuity on the wires all the way back to pins 11 and 14 on the 50-pin ECM plug and they are solid.

 

sorry for the confusion I posted in kohm it’s 2360

 

Ok that makes sense, 2.36 kOhms is 145F in the table. What doesn't make sense is that you measured that with a cold engine. Depending on your ambient temperature it should be around 10k Ohms. Do you still have the old temp sensor for comparison ?
As for the temp reading not updating, the ECM sends data to the PCM which in turn makes it accessible via OBD2. That might not be instantaneous or only when the engine is running, maybe a diesel owner can chime in here. Or you could check if the intake air temp sensor behaves the same.
