ABS Booster Assembly $3945 plus tax!!

[Ron_Mexico]

Just a FYI update, I put in an OEM sensor and it didn’t clear the issue. I then replaced the front passenger wheel bearing and it cleared everything!! ABS system is fine. Looks like a shitty wheel bearing was throwing the trouble codes!!

I’m so stoked and got new tires to mount!!

Thank you all for your help!!

You cannot test these sensors w/multimeter. Been there done it and same as you, no joy. Something about passive and active types of sensors ( go to Google and get the facts. ) I too got the ABS control malfunction code and the code for which sensor was bad but did not get the Obstruction....code.
After installing the new sensor all codes went away. So, I'm thinking you should be fine after you suitcase what's causing the obstruction code. My guess is accumulated grease @ sensor tip or grease on ABS ring serration(s). Both conditions affect the air gap and throws that code out. To clean ABS ring for front wheels, bearing assemblies must be removed, CV shafts push inwards to engine after undoing the two bolts that attaches knuckle to lower ball joint assembly ( going by memory here, so apologies if I've missed a step or two ).
