Exterior ambient temp sensor on a disco two, specifically the one that feeds the info to the display of the ambient temperature when you press the ext button on the dash AC controls.


Where is it? Because it's either moved against something warm or is faulty as I am pretty sure over the course of my driving last weekend it didn't go from -5 to 23 degrees..

Any help would be amazing

OK, here you go:

Ambient temperature sensor.
The ambient temperature sensor is an encapsulated thermistor that provides the ATC ECU with an input of external
air temperature. The sensor is attached to the cooling fan mounting bracket in front of the condenser. Part numbers:- JTF000160 or JTF000180
Easily available for about 12 quid or so. JTF000180 is most often quoted as a Rover 75 part.

Edited to include both part numbers (to add to the confusion :confused::D)

Brian, are you 100% sure that the JTF000180 rover sensor is OK from all points of view? it looks very the same but the p/n for D2 is JTF000160 actually

I took the part number from the http://www.allbrit.de/UNI.cfm?PAGE=819297&SPRACHE=EN website. Both part numbers are shown there, so I would normally use the later number. So far as the drawings show, the parts are the same. I don't know about the internals though, but seeing as both numbers are listed for the same part I would assume that there is little if any difference.
There is also a history of using some Rover 75 parts on the Disco 2.
 
IMO that's a mistake there cos it's completely unusual... the prices in that second part are usually for the same p/n genuine or pattern also ebay where the ....180 appears gaves me incompatilility with the D2 for it

You could be right, but then maybe not...:D
I've found that after looking at this on-line catalogue the numbers are sometimes different from the genuine LR catalogue which I have for my D1, also there's more information on the part in the paper catalogue, which is handy as there's some variations.

The only wrong thing with that allbrit link is that is old and some p/n's are superseded which becomes obvious when you google out the part number that's all.... i dont know how it works for D1 cos i work with the D2 version :cool:

Just purchase the genuine LR D2 parts catalogue then you'll find out the differences. :)

i've never ordered one wrong part for my D2 nor spent much time to find tyhe correct p/n online without having that catalogue so i'd better spend that money on something more usefull :cool:
 
The cost of a parts catalogue isn't a issue for me.
Fortunately I've never had to order many parts, but purchase the parts catalogues just to go with some of the cars I've owned just to see how they are built.
The D1 catalogue was the last, as the cars I have owned since I purchased the D1 I only keep 3 or 4 years so no need for any catalogues. :D
 
discool,

Wouldn't you be better off with a proper copy of Microcat to work from? At least that way if you have the VIN of the car, it will tell you if it is the correct part for that particular car. Lots of versions of Microcat around for downloading, but must be installed on a 32 bit computer or via VM VirtualBox and a separate OS.
