ABS Sensor Failure?

2011 Xterra S 4x4, 138k miles.

I was driving on the freeway the other night 60-70mph, temperature was in the mid-30s, road surface was wet. Drove over a minor ripple in the pavement, and immediately the ABS, VCD Off, and Slip warning lights came on. They remained on for the duration of the journey. When I started it up again the following morning, no warning lights were illuminated, and none appeared for the 40-odd mile trip.

Based on my rudimentary understanding of how these things work, I immediately thought that one of the ABS/wheel speed sensors had failed, but I also found it strange that it would start working again. The only way to know for sure is to use a scan tool (or pay someone to do that), but before I go that route, I was curious to see if the community had any experience with this sort of thing. Thanks!

Are you lifted with any sort of non OEM sensor wire routing? After I got my X reassembled lately, I didn't do the best getting one sense wire routed and it tangled for a bit with a sidewall. When the insulation rubbed though, it shorted the two circuits and threw lights, but when I tied it back away prior to replacement, the lights went away.

All suspension components are as they were from the factory, with the exception of removal of the bottom leaf of each of the rear springs, as they were both broken.

Front sensors are in a sealed grease environment. If the bearing assembly is making metal, I could see the signal getting screwy. All these do is report a change of AC polarity to the computer due to interaction with the tone ring. Rear sensors are "open air". Even soaked in oil from a failed axle seal they operate.

Mine threw all of these and the CEL for the pass cam sensor . but was drivable .

When I started having ABS issues, one of my front hubs was failing. And I had to replace both by the time it was said and done. Then the drivers rear outer bearing exploded. Which prompted a full rear rebuild.

Hopefully that's not the case here. It's 10 degrees outside and my garage isn't heated.

So, the lights started coming on again intermittently; once when I went over a speed bump a bit too fast because I didn't see it in time, and then again yesterday during normal driving. Each time, the lights go away after restarting the vehicle. I may just buy a scan tool to figure this out, or have the dealership look into it when I get the overdue airbag recall done on Friday.

Having it come on intermittently would suggest a problem with the wiring. Wouldn’t hurt to get down there and poke around a bit.
