For a few weeks now I've been getting that long beep showing that the parking sensors were inoperable. I bought some sensors on ebay and put them in without checking the wiring loom. Same issue. This morning I took everything apart and inspected the wiring. My OBD tool told me which sensors were having issues and i concentrated on those. Sure enough the wiring was damaged. I snipped the cables, soldered them and heat wrapped them, put everything back together and everything works great Those little saturday morning projects sure are satisfying.
