2000 Ex pulling to the left

I expect this has been covered before but I am totally at a loss trying to find it so if anyone has a link I would appreciate it and please accept my many thanks. However if not my 2000 Ex is pulling to the left when the ABS is plugged in it also has an ABS warning light showing on the dash. When the ABS i s unplugged it doesn't pull to either side. I have plugged a fault code reader in and it shows nothing at all. Any help at all would be gratefully received as I have now run out of hair to pull, many thanks

Does it pull at all braking speeds, or just before you come to a halt?
I think it can only really be to do with one of the front abs sensors.
Try cleaning the hub ring where the sensors fit.

Thanks for that I will give it a try. It may well save the rest of my hair
