Toyota Yaris 2002 ABS and ! Light

[tmontague]

Like the link that CTScott alluded to, due to the poor design of the ABS sensors on the Yaris they constantly need to be checked/cleaned to keep them corrosion free.

Every spring I disconnect my ABS sensors and spray them with a electrical cleanr and once dry I cover them in dielectric grease. I live in the salt belt and have yet to have any ABS issues. When I checked my sensors for the first time a couple years ago I was surprised that the sensors weren't that dirty.

I would try cleaning yours with an electrical cleaner and maybe even a fine bristled toothbrush if they are bad enough. Then reconnect after adding a bunch of dielectric grease. Reset the ECU and see if the code comes back on. If it does then you'll likely need new hub/sensors and even an ABS electrical connector
