No not suggesting, just discussing an upgrade. I've clocked in 70+ hrs this week so I will get to it soon.

I have to ask what seems to be the obvious question; if you expected the new sensor to read the same as the old sensor, why did you change the sensor?

Replacing all sensors with factory Mopars. All of these sensors have been replaced and are aftermarket. None of them last more than a year or 2 so I'm replacing them now instead of waiting for them to fail. Sorry if this wasn't clear.
I did use my temp gun on the t-housing, hoses, sensor & wires and got within 5° of my OBD2 scanner. The fact that there's a 10°+ difference from the Mopar to autozone sensor solidifies my reasoning for doing this. Thanks for the help.
