ABS light stays on

[polk738]

Hey guys I have a M1078A1 with the ABS light on, I believe I've narrowed it down to a wheel speed sensor problem, but I'm still not 100% sure, I was able to get the light to flash me a code 44 which says L/R speed sensor fault, I checked the resistance of the sensor but I'm not getting any reading, in fact I can't get any readings from ANY of the sensors which I find really weird, according to the WABCO manual I should get anywhere between 900-2000 OHMS of resistance but nothing, thoughts?

Clean the sensors and reinstall. They almost never go bad. I've never had to replace one. They are mildly magnetic and do pickup ferrous dust and shavings from the brakes and the road. The sensors just pull out the back. Wipe them off, inspect the hole with a flashlight and then reinstall and ensure you get it fully seated. The military opted for no backing plates to let mud and water drain from the brakes and to improve cooling. The trade off is occasionally dirty wheel speed sensors.
