Rear brake wear sensor light wont go away
So I've been fighting an intermittent yellow/red brake light and service light. The code is 071 which apparently is the rear brake wear sensor. So I replaced the sensor, the light came back on after I hit a bump in the road. I took it all apart, replaced my brake pads(they weren't close to needing to be replaced but I was upgrading anyway), and I replaced the sensor again(thinking it could have been faulty), then I reset the light. Voila! Light was gone.. 30 seconds of driving, I hit a bump, the yellow brake light comes back on for the sensor. I even took one of the old sensors and twisted the wires together with some shrink wrap, a slight bump in the road continues to cause the light to come back on.

This has been done. I am currently running with the one that has the cut off end wired together and still having the same issue after resetting the light. It's fine until I go over a bump in the road. I am wondering, could it be a relay, fuse, or even possibly a break in the wire farther up.

Yes. I've done it a couple of times just to assure that's the issue. The last drive I had I drove for around 5 minutes before I hit a big bump in the road that always seems to trigger it and sure enough the light popped back on.
