Any idea where the plug skt is from the sensor it is not obvious? Been underneath today but access is not good when suspension inactive. If it ever stops raining I will have the wheel off!

you need the wheel off , its tucked behind the plastic liner at about the 11 o clock position

Wondered if anyone has had the same problem as me with this..
HDC Inactive and ABS lights on, when diagnosed by a friend with universal diagnostics tool showed "left rear wheel speed sensor" fault. Ive changed the sensor but light still on. Went back to my mate and he says its still showing he same fault and he cant clear it?
Anyone else experienced this?

It is NOT a hard fault, i.e. it doesn't need turning off it just goes when the fault is fixed.

Pattern sensors are cr@p, always use a genuine one, make sure it is fully home and will go in and out of the hub with no resistance, if you need any pressure to push it home then grind the hole out more... ensure the reluctor ring within the hub is not full of bits of the old sensor and make sure you use the grease that comes with the genuine part... clean the electrical plug as well......  Pete

Make sure you have fiited the correct sensor for yor car , I bought one from ebay as my model was listed as correct , unfortunately this wasn't so , ended up sending the car to well known independent in ncl for diagnostics and they billed me for a repair to loom ( bullshit ) and told me the abs module needed replacement (more bull) they didn't diagnose the wrong sensor was fitted , it was only when I double checked the resistance against against the other sensors that the error was duscovered

Yes abs sensors are a pain my rear was correctly diagnosed and fault cleared as soon as motion applied. Good tip the old sensor was jammed solid only tool effective was a flat wood drill but grind the point off first and be careful not to damage castle teeth on axle. I had a front sensor diagnosed wrongly once so just change the other to rule sensors out.

Thanks for the info guys. Took it to a local indy and they saying that its showing an "open circuit" to the sensor and suggesting that its either wiring or more likely, the abs control unit !!
Ive spent a lot of time researching via this and other forums. Its a minefield lol ! Ive seen suggestions that "can bus" errors can cause these probs?? I have changed some of the bulbs for led's - might try changing them back just in case.
Also thanks HAYLANDS for your input - the sensor I have fitted was VERY tight going in, maybe I should remove again and clean the casing some more?
