It's more common for wiring to be an issue with failed sensors than you'd think. If you're getting an error for your water in fuel sensor, and it tests fine, there's a chance that the pigtail has failed. Fleece Performance offers a replacement pigtail for the 2011-2016 6.7L Powerstroke so your Ford will quit throwing that silly warning light. Also, don't worry if you damaged the wiring during an install, Fleece won't tell anyone, and fortunately it is a cost efficient fix.
