sometimes abs light is on
Turn off the ignition after the Open abs light off. When the enters a bad road, abs light on ?
the computer detected a fault right wheel
I cleared right and left sensor
but now the abs light is on continuously
What else can I do ??

How did you clean it? Most probably you damaged the sensor while cleaning. New ones are expensive, something like €175,- each..
Replacing is easy. One nut holds the sensor onto the rear of the hub, then follow the wires and unbolt them from the controlarm, disconnect the plug that's above the inner wheelarch

ok no problem i make and abs run, because sensor wire broken
