MikeD Posted July 1, 2019 Share Posted July 1, 2019 Dismantling an RRC and have a small sensor that came off the drivers side headlight panel and no idea what it is for It is connected on two wire, one of which is Red/Slate, anyone recognise it?

ThreeSheds Posted July 2, 2019 Share Posted July 2, 2019 I found one on mine a few years back and assumed it was an ambient temperature sensor... I left it alone and it left me alone... Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted July 2, 2019 Share Posted July 2, 2019 I don't remember seeing one on my Vogue SE, with AC, but could be an outside temp sender? Quote Link to comment Share on other sites More sharing options...
MikeD Posted July 2, 2019 Author Share Posted July 2, 2019 I forgot to say this was a 92 Vogue EFI with AC and this didn't have any form of temperature readout on the dash it looks like it could be a temp sender but it only measures 0.3 to 0.4 ohms at room temperature. it does measure the same in both polarities and I guess it may change with temperature I am not expecting it to have any value but was more curious to find out what it might be I spent a long time looking for online evidence of what it might be and even spent time looking at wiring diagrams to see if I could spot Red/Slate wire colours Quote Link to comment Share on other sites More sharing options...
ThreeSheds Posted July 2, 2019 Share Posted July 2, 2019 Mine was a 90 Vogue but with no AC - I thought it might be something to do with the injector inputs (although thinking about it they would just get that from the MAF sensor I would have thought?) Is there an ice warning on the dash - could it be for that? Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted July 2, 2019 Share Posted July 2, 2019 I'm not sure that is a factory plug to be honest, perhaps something aftermarket? Traced it back? Quote Link to comment Share on other sites More sharing options...
MikeD Posted July 2, 2019 Author Share Posted July 2, 2019 it must be oem as the wires from the plug go into the main car loom in the engine bay, not easy to trace once it is in there. I may find where that colour comes out i'm sure I will find out what it is for when I cannot get something working on the engine 😀 Quote Link to comment Share on other sites More sharing options...
steve b Posted July 2, 2019 Share Posted July 2, 2019 I pulled one off my old D reg 200Tdi RRC when I broke it up , I'm pretty sure it's an ice alert sensor ? Mine had AC too for info. It's still around somewhere in one of the odds and ends drawers in the tool box , whenever I see it I always think " must take that indoors and put it in the freezer to see what it reads " then forget about it 'til the next time... cheers Steve b Quote Link to comment Share on other sites More sharing options...
MikeD Posted July 3, 2019 Author Share Posted July 3, 2019 Just found one for sale on ebay as a Range Rover Classic RRC Heated Windshield Washer Temperature Sensor Switch but I didn't have a heated windscreen and the sensor isn't anywhere near the washer maybe it is supposed to switch the squirter off if the temperature goes below freezing just chucked it in the freezer, probably find it in my dinner next week 😂 Quote Link to comment Share on other sites More sharing options...
walace58 Posted July 3, 2019 Share Posted July 3, 2019 Might switch on heaters for the headlight washers Quote Link to comment Share on other sites More sharing options...

What walace58 said, read heated washer, rather than heated windscreen. I've often wondered how the car knew when to heat the washers. Also the how a RRC knows to activate the heated door locks I found in mine, albeit not connected. Intended for Scandinavian climes I believe.

teabag Posted July 4, 2019 Share Posted July 4, 2019 Air Con... BTR9733 solar sensor Quote Link to comment Share on other sites More sharing options...
MikeD Posted July 5, 2019 Author Share Posted July 5, 2019 @teabag, looks similar but this is from a classic rather than a P38 so not a BTR9733 If it is a switch to turn the heated washers on then it must be broken because it was 0.3 ohms after being in the freezer for 24 hours and 0.3 ohms several hours later when it had got up to 26.6 room temperature Quote Link to comment Share on other sites More sharing options...

MikeD Posted July 10, 2019 Author Share Posted July 10, 2019 @teabag - spot on, well done now I know what it is I found an old thread on here where the identical part had been discussed in 2007! https://forums.lr4x4.com/topic/14516-can-you-identify-this-component/ shame that after all this it appears to be faulty but it exercised the grey cells for a while and at least I know this won't be why the engine doesn't restart when I eventually get around to connecting it to fuel and volts 😁 thank you to everyone who participated Quote Link to comment Share on other sites More sharing options...
Si J Posted April 5, 2022 Share Posted April 5, 2022 I know it’s a long shot but do you still have this as i requre onefor my classic. its the sensor that activates the screen washer jets when it below 3 degrees Quote Link to comment Share on other sites More sharing options...
Snagger Posted April 6, 2022 Share Posted April 6, 2022 Glad to hear definitively what it is. My 95 300Tdi manual (no factory AC or heated front screen) has it. Quote Link to comment Share on other sites More sharing options...
