B011FFluid Reservoir Level Sensor D
- Generic OBD-II code · Body
- How the car detects it
- B011F reports level sensor D. A recurring weakness of float switches in washer bottles is motion: fluid slopping around in corners or under braking lifts and drops the float and can set it spinning. Continental's patent US9003878B2 answers with a float guided in an angled carrier, ribs that stop it turning and an optional slosh guard, so one design suits side or bottom mounting. The other weak point is the wiring: FCA parts tip 68225064A tells technicians who face a false low-fluid message to check circuits W1 and W11 at a 48-way connector before condemning the float sensor. Which tank letter D refers to is left open by the makers, and nobody documents B011F publicly. Expect flickering or false level messages.
