P0172 is a trouble code that is set when the ECU senses that there may be too much gasoline present in the air-fuel mixture of the engine. A proper air-fuel ratio of about 14.7:1 is vital to obtain maximum engine power and fuel economy
The fuel mixture grows rich and eventually, the code sets. An "over reporting" Mass Air Flow Sensor can be a common cause of a code P0172 and P0175. Essentially, this means that the Air Flow Sensor is telling the computer that much more air is entering the engine than actually is.

try taking a pin and cleaning the holes on the squirters and if that does not work check the washer pump it is located on the washer fluid tank

If you live in the US, take it to qany Auto Zone store and thy will read the codes off for you, I would suspect any right thinking competitor would do the same, check if you don't have one near by.
Hope this is of some help.
