Year of Manufacture *: 2004

Hi

ABS light on brake pedel vibrates when braking on occasion. Put it on solus came up o/s/f and n/s/f sensors faulty, disconected sensors and scoped them got no patten, checked pickups on driveshafts no cracks and very clean,scoped one of back sensors for comparason and got good pattern.gues what fitted two new sensors still no pattern,then in my wisdom did resistance check, old sensors and new sensors all ok.where do i go now. Any help welcome.

PS gaps between pickup and sensor fine.

Philip

Hi Philip

I am not familiar with what system is fitted to this vehicle, but I would recommend leaving the sensors connected when carrying out the scope test as some sensors will not produce any output if disconnected.

Philip.
What system ? Bosch 5.3 ? Air gaps are fine!! what are the air gaps ?
Even if the drive-shaft,s were wrong (ie amount of teeth/spacing)you would still get a siganl all be it of the wrong frequency/voltage.

yes kev you are right but signal was so small had to reset scope to pick it up.removed rear disc to compare pickup ring and its teeth are three times as deep any one no if this is normal. When driving rear wheels register at least twice the speed of front, car gone now but is coming back at some point.
