I was driving along when I heard a strange clunk sound. I thought I ran over something. A few seconds later, my ABS light came on. It's done that before during hard breaking, but after a "reboot", the ABS light is gone. This time it hasn't gone away.

I did a search, one cause is dirty sensor/s. That might be the case because it's rained every other day for 2 months and I have not washed Skull-1 since. Are ABS sensors capable of falling off, and will I be OK till I can take a look around?

 

Now I get a low traction message. I pulled off the 2 front wheels and inspected everything. I searched and came up with dirty ABS sensors. I know I heard a noise that triggered this though.
