Hi, i have a problem with my abs, it faults as soon as i start to drive. i have had it scanned by a local garage and the fault it is giving is LH rear sensor consistency and RH rear sensor consistency. i have had the sensors tested and they both give off an ac reading when in use suggesting that they are ok. i have had them removed and cleaned and also had where they are mounted on the car cleaned and the air gap reset but the fault remains. is it unusual for both rear sensors to show faults at the same time? i have read much about the problems others have had with these problems and wondered if anyone has any other suggestions?
