Default thermostat sensors?

Hi Everyone.

2005 ford ranger xlt v6 4.0l 4wd...

I have two sensors on my thermostat housing unit.
engine light came on after recently replacing housing unit and thermostat.

WHAT are the two sensors???
are they the same?
is there a difference between the two?
which is which???
and what would be their part number(s)?

Thanks every one!

one is for the PCM other is for the gauge

they are the same, one sensor is a sending unit for the gauge in the truck, the other one is a sensor for the PCM that tells it when it can enter closed loop and when the engine is at normal temp

The two temp sensors are Not the same one is a one-wire temp sensor and the other is a two-wire temp sensor. the one wire sensor is for engine temp to the temp gauge and the two wire sensor is for temp info to the ECM.
