Abstract
A sensor system includes a pump, a valve supplied from the pump, a sensor fixed relative to the pump, a nozzle supplied from the valve and aimed at the sensor, and a computer communicatively coupled to the pump, the valve, and the sensor. The computer is programmed to instruct the pump to operate; while the pump is operating, instruct the valve to close; receive data from the sensor while the pump is operating and the valve is instructed to be closed; and set a flag upon determining, based on the data received from the sensor, that the nozzle is outputting fluid onto the sensor.
