'95 Expression ABS Sensors.

[Roadie49]

Hi Folks,

I have a non operating N/S/R ABS sensor that needs to replaced at some point. I don't have problems with the Dealership getting their listed part, but I do have an issue with getting one that is a direct replacement for the one that is fitted. I'm finding out, as I did with the clutch issue, that the last batch of Cavaliers seemed to be fitted with production parts from other models, hence the Calibra Flywheel / Clutch etc .

I'm guessing that the rear ABS sensor is from another model, too. I'm surprised that the folks at the dealership parts dept don't seem to know what bit was fitted to this model.

Mine looks like this . . . .



The one the spares sent was this . . . .



I'm a bit worried about yanking the old one out until I have a spare. As you can see, it's fairly well rusted in.

I don't suppose shorting the cable out would be a temporary fix, just to turn the warning light off.

Any light that you could shine on this issue would be most helpful.

Thanks,

Chuck

On the Cavalier, the rear abs sensor is built into the rear hub.
It is not a separate part that can be taken off the hub.

So the bad news is that if the rear sensor needs to be replaced, then you will need to fit a complete hub.



Typical Ebay prices for a complete hub are £50 to £60.

The one pictured looks like a front sensor.

I agree...
Your picture is a front sensor.
A main dealer should know better.

I had one of my front sensors play up (same as in photo) which was originally retained in an aluminium housing, corrosion within had almost totally crushed the sensor! Wish I had taken a photo.
New housing was made of plastic and with the original crushed sensor installed has been working fine ever since!

That's good information Chaps. That certainly looks like the culprit. Armed with this knowledge, I shall call back to my local supplier of handy bits and pieces, rather than the dealership. Thank you for your advice. Greatly appreciated.

Cheers,

Chuck

Spotted a brand new one at Autodoc, Germany. Will take photos and details to the garage tomorrow.
