How can I bench test the EGR temp sensor?
Do I heat it with a flame or will boiling water work?
Am I looking for ohms Between the two pins or straight continuity?

Hi cheetahchrome, Welcome to 2carpros and TY for the donation You measure the sensor's resistances in a given temperature-see below

I can assume these numbers are gathered by testing the sensor in hot water since the temp only goes up to 212?

The resistances of the sensor drops as temperature increases between 32deg-212degs similar to a coolant temperature sensor if its not within range replace the sensor--
