EOT less than ECT

For the past few days I have noticed the EOT is running less than ECT. The ECT still sits around 192 or so like normal but the EOT is only getting to 175 to 185, usually it sits around 195, this is after driving on the interstate for 30 minutes or so. Is there anything else besides a bad temp sensor that would cause this. They show the same temp after sitting over night.

Thanks

You might try switching the sensors (they are the same) and see if the temps swap or stay the same. I, personally think you have a bad EOT sensor.

Before switching the sensors, see if the temps are the same (or real close - plus minus 3*) BEFORE you start the engine after a 16 hour no run condition.
