1. A system comprising:
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;
wherein 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 while the pump is operating and the valve is instructed to be closed, that the nozzle is outputting fluid onto the sensor.
