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

That is the air temp senor I think, someone will correct me if I am wrong.

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 '06

Just went out and looked at my '05. Same color grey. It is plugged into a blue plug with the green lock you can see in your picture. The blue plug is taped over in your picture.

Jackatg450, does yours just lay there in the same position as mine? And what does it sensor?

 

[xoxoxoBruce]

Incoming air temperature.

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.

Thank you Dick, I now know why guys & gals prefer an 05 or an 06 ... so they don't have to stick their arm out the window to check the temp :laugh: :laugh: :laugh: plus it does not put "miles" on your window motor !!! tennesseecozydog :ssr

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".

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

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.
Personally I do not think it is a very accurate read anyway. Maybe +/- 10 degrees?

Outside temp gauges are pretty iffy anyway. Mine is so hard to read and only goes from 20 to 100 in 20 degree incriments. So in the summer it is 80 or 100 even thouigh it may be 120 outside. Very hard to read with any accuracy. Thinking about getting Digital someday.

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]
