XJ40 ABS Wheel Speed Sensors

[spottroadgarage2006]

Hi Does anyone know if speed sensors from various other models will fit a 1993 4Ltr XJ40 Daimler specifically the rear right hand side. I expect that the wiring may be different but this can always be extended if needs be. Most of the usual suppliers have them listed as NLA. One or two are available in USA but the price is astronomical and I shudder to think what our customs revenue agents will do to any imported item. I have seen them listed on a couple of suppliers sites at around £160 each but then listed as not available. Second hand ones from an unknown source are always a big risk. This is a part which could be a candidate for listing as one for consideration as a future must have with possible suppliers.

Theres certainly quite strong demand for these since they can be very hard to remove without damage on the rears.
I suspect if they were ever to be remade, the price would be even higher than what you have seen. Based on other pricing coming on New stock from JCP.

One thought that occurs to me. from 1997, on the late X300 models, and all through X308, they used a plastic housing on the ABS sensors. I suspect because they were cheaper to proceed, but at least on the plus side they don't tend to stick in like the metal bodied versions.
Now of course the plugs are are different on those, but its the same principle and they fit in the hole ok. So you may be able to adapt the connector plug, as they are still a two pin plug.

One other thing to note, on the XJ40 sensor, they use a Coaxial still cable (no idea why?), where as on X300 onwards its not (more conventional twin wire affair.)

From my basic "electronics" knowledge going back a good few decades, a "coaxial" cable is used as a "screen" to keep out external interfering "extraneous" (spelling ?) signals ....

Note to self :-

Now then, why on earth am I posting on here at 6am in the morning ?

1. There were 3 or 4 different version of that sensor, they are not compatible, from what I remember?(or am I talking about 300 ones now? )
2. Even if you can fit them in(one version wont fit the other), they wont work.
3. The 300 are as crappy as the 40 ones, they are plastic but still fit in a special sleeve, or its metal in a plastic sleeve that are always fused anyway
4. To remove it without destroying it you need the hub on a bench, otherwise I'd be very surprised if anyone could do it!

The x308 and later cats are a different kettle of fish, come with cheap and fairly easy to remove sensors. Jaguar eventually learned a lesson here.

This forum has a description of how you can deal with this problem. It might come in handy. I think to try.

I managed to find one NOS for mine, the other had to be a used part. There is a Renault sensor that fits with some modification I believe. I think it'd be nice if some parts suppliers could reintroduce these XJ40 sensors though
