What is this sensor? Is it supposed to be plugged into a socket? It is in front of radiator.

If it is a sensor it would be the air temp for the DIC and Aux temp gauge. If it is a connector it is where the sensor would plug in. My sensor is black and a rectangle, but my trucks are '06That is the air temp senor I think, someone will correct me if I am wrong.

Thanks, if you look at the picture you will see ears on the plug indicating it fits on a socket somewhere close. I see no hole any where or did GM just tape it to a harness. And being that close to radiator you won't get a accurate reading. It's really no big deal, but "Inquiring Minds Want to Know".You are looking at outside temp sensor on 05/06
03/04 do not have outside temp sensor.
03/04 owners just put the window down and stick their head out for temp.

I think SWT RYD was commenting that the position so close to the radiator will cause it to be warmer than the air temperature in free space and therefore it will be inaccurate.I believe that GM also used this same sensor on some cars as the intake air temperature sensor and it was "snapped" into the air cleaner box. So they just incorporated it into the wiring harness an located it out front where it would be least effected by the heat under the hood.
It is a thermistor - resistance varies based on temperature and the resistance will vary no matter where it is placed
thanks that makes sense just to put it out there then people wonder where it goes I'm not going to use it anyway but I just wonder why was just laying there and not plugged in in it thanks appreciate it]I believe that GM also used this same sensor on some cars as the intake air temperature sensor and it was "snapped" into the air cleaner box.
