Since everyone here was saying it was a corrosion problem with the connector in the hub assembly, i gave it a try and repaired it myself.

I opened the connectors, used WD-40 to wash the terminals inside the connectors, cleaned the connector of the WD-40 with some airpressure and then filled the connectors with dielectric grease (even tho regular grease protects from corrosion, the grease itself conducts electricity and could cause some weird shorts between the two terminals, dielectric grease prevents this).

I did the repair january from last year and its been working fine since then. I think i will reopen the connectors and redo the same job before it gets cold just to be sure everything will continue to be fine.

If your harness / sensor connector is in really bad shape, this repair might not work but for the price its worth the try. (took me between an hour or two and cost only the 6$ dielectric grease tube and some wd-40). Also, i used wd-40 but I guess connector cleaner would make a better job.

Just had this issue. Warranty lapsed. I am not a mechanic, does anyone have pictures where these contacts/connectors are so I can clean them?

I can take some pics but it won't be until summer ... since I don't have a garage where I can work in the winter.

But if you need to do it now you can always take a look here http://www.etimago.com/yaris/repairm...%20Control.pdf

Page 97 is where the installation/removal diagrams are for the ABS sensors are on the front and rear wheels.
