Another ABS thread!.... More Abs woes....
 

My speedo has stopped working and my ABS light is on.... its an MG ZT diesel......

I've replaced the ABS sensor on the drivers side this morning, twice, with two new ones I had in the attic, this was after freezing outside drilling out the old one which refused to give in to me!

The original problem seemed to be damage to the cable, because I twisted it about where the outer sheath had been worn through, and the ABS light went off..

But neither of the new cables seems to be working.... any suggestions :shrug:

Thanks & regards

if you drilled it out you may have drilled too deep and damaged the bearing

Thanks, but pretty sure I didn't go to deep as I removed the 'sensor' end intact when pulling out the remains of the unit with pliers..... any way I would know for sure?

if the original came out undamaged then you haven't


try this thread for some more help

I'm not the most informed on these matters, but my ABS suddenly became faulty on the front nearside. I traced as you a faulty outside wiring.

Unlike you I couldn't drill mine out and had to get a secondhand hub fitted as even the garage couldn't get it out.

What they did find though was that just beyond the plug that vanished into the engine bay there had been a short and the wires had fused.

A replacement plug cut and shut and new ABS sensor from a well known auction site resolved it all. Light now out and my cruise control is working again

:}

When I say the end came out intact, I am referring just to the very end where the sensor has flatted sides.... just one question before I start going through all the tests next weekend... I cleaned out the hole with cotton buds / meths and blowing out any debris, but did smear some petroleum jelly on the new sensor to help it back into place. I don't think this would have any effect on the magnetism .. but who knows!
Thanks for the pointers so far...

If you get an ABS plug and socket from the scrappy and fit an extended cable between them you can plug any ABS sensor into the NSF and see if the speedometer then works, which should help narrow down the fault.

If none of them get the speedo working then check the ABS modulator plug connections - not unknown for them to corrode.

More work for me next weekend then, hopefully I'll get a dry day as no garage!

Why didn't I listen to that voice in my head that said 'just tape up the wires' on the original when the ABS light went out.........

might be worth putting the original back in....just in case there's another fault
