ABS warning light without obvious sensor issue

[yxd0018]

Last time when abs light is on, I found one bad sensor and replaced it. Now the ABS light is on and off (most time it's on). All sensors have the right resistance. Then what should I do?

remove them and check them out, but if you're like me, ever single one will be stuck and break on removal. You can get them very cheap on amazon/ebay. When one of mine was bad I got all 4 for like $40 and haven't had a problem in the year they've been on there.

Isn't electronic sensors not suggested to buy from amazon/ebay? I was burned before for aftermarket electronic parts on ebay. Its' $20 on FCP each.

Most common the sensors get dirty, they are magnetized and picked up rust. They can be cleaned, I did mine recently.
