Hi
Hoping someone can help... I recently installed a new speed sensor (front passenger) on a 2011 infiniti M30D. I had to drill the old one out so its in bits. Only problem is I'm still getting an ABS sensor error. If I clear the codes using an OBD2 then the light stays off for about 100 metres then comes back on. What ive noticed is if I choose live data on the OBD2 all the speed sensors give roughly the same speed, including the front passenger. But for some reason it will randomly drop from say 40MPH to 25MPH only for a split second but that seems to be enough to cause the error. Anyone have any ideas why its doing this, like i said i did drill the old one out so could it be that Ive damaged the hub
Thanks for any help
Mike

Are you still using the generic off brand abs sensor?
Maybe you damaged your wheel hub or knuckle when you drilled it out? Used knuckles are pretty cheep and they seems to be the same on every nissan model that uses these akebono sports brakes. 370z and Q56/60 uses the same knuckles and some on ebay might come with the hub already.

IDK if the hub is the problem unless you drilled really deep. There's a cut out in the hub that the sensor fits into so maybe you went too far and damaged that toothed ring that the sensor uses to calculate the speed or your generic abs sensor isn't long enough to register the toothed ring

Hi
Yeh I checked behind and I'd drilled into the cog..
