Default ABS Sensor

Hi there,

My left side rear ABS Sensor is broken on my XJR and Iím struggling to find a replacement. Iíve contacted a few breakers who couldnít get the part out and Iíve looked around on eBay and canít find the specific one. Not to mention Brit Car wants £217 plus Vat for it. A couple hundred more and I could buy a beat up XJ6! The part number is LNA2223AB.

Any advice would be appreciated.
Thanks.

There is a reason why good, used rear ABS sensors are so rare in supply - they are a pig to remove from the donor car, and are often broken during removal. Learn how to remove the wheel sensor without breaking it before you decide to acquire a donor car.

Hi. Iím currently looking into replacing my rear hub carriers with the later x300(vin from 801672) or x308 parts so I can use the newer, cheaper and more available abs sensors! As far as I can tell they should be a straight swap with just a bit of wiring to connect the new sensors to the existing loom.
If it works I should be able to change both sides with secondhand parts for less than the cost of 1 new sensor.

Yes, later editions of the X300 have different ABS wheel sensors. Let us know if your experiment works out.

Here are two old threads about earlier attempts to tackle the rear ABS sensors:

I'm only finding front sensors available on eBay! They must be easier to remove intact than the rears for some reason?

Hi, I now have a 2001 X308 hub carrier next to my 1996 X300 (X305) for comparison


No obvious difference other than the ABS sensor

Same number of splines for the half shaft

Slightly different looking hubs

Iíve ordered the harnesses to connect the new style sensors and will look at the difference between the connectors under the rear seat next.
It will be a while before Iím able to test the theory further as the sub frame is on the garage floor awaiting a refurb.

I have a feeling(might have read it somewhere here) that x308 might have a different ring gear, hence x308 sensor cant be used in an x300 hub, any chance that you could compare them? If they are the same then I cant see any reason why one couldn't fit an x308 sensor in an x300 hub with an extra wiring loom from x308.

Looking at the ring gear they both have the same diameter, tooth count and sit at the same depth in the hub carrier! Also a quick check on jag classic parts they share the same part no. CBC4705

I did read a thread sometime ago that said it was possible to use the newer sensor in the old hub carrier (or was it a front sensor in a rear hub?) but some fabrication was involved

Iím guessing at least a new hole drilled and tapped to keep correct orientation of the new sensor


X308 sensor in x300 hub carrier, not sure thereís enough room to plug it in behind the brake disc guard

Sensor mounting point x300 on left vs x308 on the right

Incidentally I got the old sensor out (whatís left of it) by gently tapping and pressing from inside the hub carrier but it deformed before it moved making it I would say near impossible to reuse one after its been removed

The other thing I noticed while looking around jag classic parts; some of the part numbers around the hub area change after 2002 on the x308 so not sure if they are still compatible with the older models

I found this to be the case when my 97 donor car had different sensors to my 96 daily driver. I remember that one was longer than the other, but can't remember which was which.

Just read a post on Facebook's Jaguar XJ X300 Group where someone says the rear ABS sensor of Audi A4works a treat and costs GBP20 (obviously aftermarket product). Am waiting for a success story from this forum.

Iíve read the same recently but it appears you still need to change the connector and make a spacer as the body of the sensor is slightly longer on the Audi part..... still a lot easier than changing the hub carriers but as my sub frame sits in the garage awaiting a refurb Iíll slowly muddle on with the experiment, Iíve not seen anything yet that would suggest it wonít work!
Iíve also had confirmation from another owner who replaced the whole sub frame with one from an X308 all he had to do was change the connectors on the sensors and they work on the X300

I read somewhere where the direction of wheel rotation and the relationship of the mounting ear makes a difference in working or not

In choosing a substitution a left for a left or maybe left for a right

Without the trouble of getting a connector match a waterproof splice or what's called a environmental splice of the 2 wires will let you swap polarities electricaly and solves the problem of pulling the rear seats out

The environmental splices are hard to ind but I have a source if you PM me I will mail some to you for free

Guys, i did it A4 sensor works in x300. You need to use washers as sensor is longer and use the plug from your original sensor. It works perfectly

I think they were talking about an aftermarket ABS sensor (Ref. NTY HCA-AU-002) intended for A4 model year 2000 to 2005. Here is a link to the FB discussion.
