Method of checking wheel speed sensor fault

Hi Pedro
How do you pull them out????
Havent tried yet as Im waiting for a spare one to turn up.
Andrew

t'is easy!
remove wheel, caliper, hub, small allan screw,
gently pull sensor up and out,,

I'd have a stiff brush handy at the allan screw stage and clean up the area around it before removal.

should release with a gentle suction "pop"
there is a small o ring-- dont lose it!

Mine were 4 times what the single wheel should be reading for the same rpm in 5th at idle,a tad harder to check in your self shifter,but you should have a rough idea.
Hope you get hold of a sensor from the supplier I mentioned in the PM,I didnt want to know what a newie is worth!!!!

Was hoping Pedro discovers the same as I have so in future Pedro and myself can pass the correct info on to D2 owners as its such a common fault.
Ive got a secondhand sensor coming,will see if it fixes everything.
Thanks

OK,, so several brake tests done and witnessed by reliable mate,,

the only wheel that locked was the wheel that DID NOT produce a speedo reading.

felt a reduced ABS pulse during each test.



cheapest sensor I can find is 175 from andersons in hervey bay,,,,,,335 from LR

anybody got any other suggestions??
testing OR pricing?

Try Bundalene on Ebay.
Ive got a S/H one on the way.$55 inc ph.
He has more stuff than advertised,find his ebay shop and email a question.
Nice helpful person.
Andrew

yea,, already have;)

and ---- no.
has lots of D2 electrikery but not a front sensor,,,

UNFORTUNATE!!!!!!
Try Karcraft,inc postage they are always pretty good.

Hi Gents
Just logged on to see if anyone has had this problem, it seems to be quite common. As a matter of interest my 2001 D2 has done 206,000km. Is this ABS fault a sympton of age or abuse? Or just another Landy built in headache. :mad:

Fairly common.
Off-roading seems to make it worse,mud/water/dirt seem to make maters worse.
Andrew

Andy I cant see how anything would get in there,,
from my small look it seemed a sealed part of the hub that the sensor uses to read off,,,


maybe heat???

Ok
Fitted secondhand sensor.
Same problem.3 amigoes and no speedo reading from that wheel.
The secondhand one reads just outside the recomended value(950 to 1100ohms),1130 ohms.My other 3 that do work the speedo read similar values.ie just over 1100 ohms.
Im getting the same ohms reading at the SLABs ECU input for that wheel,the value also changes if the wheel is rotating indicating that the sensor is OK(in my opinion).
All fuses connectors checked.
Starting to belive there could be a fault/dry joint in the SLABs connection.
BlkNight Dave,this could explain your ability to induce the fault in yours by wriggling the harness.
THOUGHTS PLEASE PEOPLE!!!!
Thanks
Andrew
