Oil temp sensor voltage

Is there an acceptable operating range of voltage for the oil temp sensor?

I recently took my truck to the dealer because my diag tool was showing 40-50* deltas...and they did their troubleshooting and filed a report of no more than 9* deltas...

My tools reading a Eot of 225* with a sensor voltage of 0.77-0.72 v.

Does this sound right?

How does the ECT sensor read? I think the 2 sensors are the same. Could swap them and see what happens.

ECT sensor:



EOT sensor:




Same number on each.

I've used different tools but all weren't able to read Eot so I don't have a comparison yet...the ect all read within 2* of each other so I'm pretty confident the coolant temp system is good.
