I have dreaded 3 amigo's again stuck new hub on about 2 years ago as wheel bearing collapsed all was well until a few months ago lights came on showing erratic sensor then after awhile no reading from sensor so replaced sensor and today reading erratic sensor again when I plug diagnostic in and read live data it seems fine as it is reading speed from the sensor. back a few months ago diagnostics said stuck abs valve but it hasen't showed since. Just wondering if faulty shuttle valve could be causing this but only showing it as abs sensor fault.
