B0116 covers actuator N. Like B0111 it also turns up on the 2004–2009 Toyota Sienna, where bulletin T-SB-0069-12 uses it for an open side-airbag squib circuit, not a washer. In the generic sense, cold is a typical burden for camera washers. Denso's patent US9180840B2 mixes air from a pump with fluid admitted by an electromagnetic valve and adapts to the weather: at or below a threshold such as 2 °C it lowers the pump voltage so that larger droplets form, which freeze less readily on the lens, and it lengthens spray and blow times. Kautex offers heated nozzles and heated hoses against the same problem. Frozen fluid can stall a pump or valve and make it draw abnormal current. Which camera N serves is not published.

Likely causes

Washer fluid without enough antifreeze frozen in pump or valve N
Actuator N electrically open or shorted

Symptoms

  • Camera wash fails mainly in frost and recovers after the car has warmed up
  • Ice or salt film stays on the lens of the camera served by actuator N
