Unhappy 2001 Ram Outside Temp. sensor

I have a 01 Ram 3500. The overhead temp reads -40. I did the internal dianogstics and it reads pass. So my guess is the external sensor. My question is, where the hell is it - exactly. I've heard a in the grille, the radiator support etc. Any help would be appreciated.

It should be behind the grille, to the right of the radiator, and to the left of the headlight. There shouldn't be anything else nearby that it can be mistaken with. Hopefully someone with an 01 can confirm this.

NO! Dodge changed the location in 1998 I belive. Anyway.. When you open your hood, look up and it will be right above your head. The wire runs from the under hood light. Cant miss it.

Okay, I went to the dealer to get one and it was wrong. They say by the bumper. The plug is clearly under the hood. The sensors are not the same. Does anyone have a part number? The dealer cannot seem to get the right one. Mine is an 02 2500.

Nice job on the thread search. Here's one listed on ebay that looks like the one in mounted to the hood in my 2001 2500. The listing says it fit's the 02 as well. Dodge part number 4688204.

Temp sensor

So does anyone have the proper part number for the ambient temp sensor? I can't seem to find it anywhere.

9This is the ambient temp sensor for an 02 2500. Standard Motor Products # TX49 Located on the inside front of the hood. If that's not it, then you are either looking at the wrong sensor or dodge changed to an 03 setup that I don't see listed anywhere.

That is the one they keep giving me, but it doesn't fit anything on my truck. The connection is not so square. I believe my sensor is right beside the hood light. Can't imagine what else it could be. The sensor itself is gone so don't even have that to go by. I have read on the forums that is the proper location for 98-02 but can't seem to get a part number.

Seems to me you are missing the harness that goes from the plug by the hood light to the temp sensor.

Well, some guys say under the hood by the light, some say by the latch. There is no plug by the latch, and one by the light. Temp sensor does not fit it though, Cant imagine what else it would be for. It shouldn't be this hard really. The missing harness thing makes sense but why would they run a harness from the inner fender well, up the hood, then back down to the sensor? Unless it is because it is part of the hood light harness. Wonder if that can be bought?

The sensor does mount by the latch. What part of "your missing the wire harness" do you not get? My truck does not have that option. But there is an empty plug mounted just before the hood light. You need the harness that runs up to the front of the hood for the sensor. Simple as that.

Went to JY today. Tried to find you a harness, but none of the rams had the overhead read out.

There was a 97 with one, and yes 97 back is located next to the driver headlight on the rad support. But that's not what you want.
