Default OHC temp question

Installed the OHC in my 2002 and am pretty happy with how it looks. Slight issue is that the temp gauge seems to be reading about 5 deg too high. Temp probe is located behind front bumper to the right of the bumper mount. Any way to calibrate these, or is the probe just in a bad location? Thanks for any advice.

What are u basing the temputure off? News radio cell phone?

Mine will read a degree or two higher then the news or radio says but is spot on with my phone.

Your location is about where I got mine. As long as there is no direct wind or engine heat ur fine.

Basing it off of Iphone data. I do not have a valance on the truck right now so wonder if that is allowing too much wind to hit the sensor.

If it is not blocked then yes it would.

Try placing it up behind the grille.

i put mine in about the same spot as it came off of the explorer on the right side of the core support... i think it may read a degree or 2 off but i'm good with that...

All these answers are pretty useless, picking a location out of the wind away from the engine heat bla, bla, bla is covered in all of the how to's. I think the question missed is "can it be calibrated"? Bueller, Bueller?

Could someone please explain to me how WIND would cause the temperature reading to be off? It's not a person, wind chill doesn't effect inanimate objects. Wind will not make it read an incorrect temperature. In fact, it will make it read more accurate.

I am full of good information today. While I was concerned about my temp variation, I did not mention that my valance was off the car waiting for the new one to show up. Came in yesterday and I installed and guess what, the temp now reads what my iphone states (within a degree or two). I guess the probe was a bit too much in the wind. Looks like this is a fix for now.

No it wasn't. Actually just the opposite. Please think about this a little more than what you feel on your arm when the wind blows. Wind is air. Air temperature is air temperature regardless of how fast it is moving. If it is 80 degrees outside, and there is a 65mph wind blowing, then that is an 80 degree wind too. Your temperature sensor, and any other thermometer or sensor, will read 80 degrees regardless of how fast the wind is blowing over it.

We as humans (and any other animal) feel "wind chill factor" because heat from our skin is being removed at a faster rate when air is moving over it. Therefore, it is felt as being cooler. This only applies of living creatures such as people, dogs, and giraffs.

If your sensor was reading too high, it is because of engine bay heat reaching it and "contaminating" its air sample. Those valances do have a purpose when it comes to air flow under the truck. By putting it back, it now allows the air to flow as it was intended. In reality, it is ALLOWING the wind to hit it and preventing the engine bay heat from reaching it.

I know this is an old post, but I am still looking for the calibration procedure for the OHC temp sensor...I know if you hold the mode button down, it goes to VAR, then to CAL, then to CALt...which I assume is temp, but what temp does it need to be at for that?

ALSO...FIRERANGER is 100% correct, I keep seeing all these posts about the vss correcting for windchill, lol.
