Windshield washer tank level sensor location

My wifes 2009 Prius has the windshield washer empty icon displays but the tank is full of fluid. Rear wiper sprays but the fronts do not. I see only wires leading to the tank with the dual spray motos but where is the LEVEL SENSOR located. Suppose to be in the tank but I don't see it on the vidoes of replacing the tank. I think my problem is the sensor is bad but it does not stop the washer fluid from spraying so that means one tank motor is bad or no voltage to it.

 

I looked at all these Utube videos on tank removal and installs but all of them show the twin washer motors and unplug them...no sensor shown.....I guess I will buy two motors (because its the wife !) or whole tank and 2 motor setup to do this only once LOL!
Thanks for the quick response...

 

Alright ya'all....mystery solved and APOLOGIES on this wild goose chase......The indicator on the dash is NOT the LOW washer fluid icon but the Windshield defroster icon displaying that it is ON. I took my wifes word for it and did not validate her claim as she told me the windshield washers (Fronts) did not work either....threw me off even though I am a retired prof mechanic with 50 years wrenching in the fleet repair profession...2004-2009 Prius does not have a LOW Washer fluid sensor. I have the 04 and the wifes the 09. I ordered an Amazon washer pump so that should take care of the problemo....I thank everyone who participated !

 

I took my wifes word that the icon displayed was for LOW Washer fluid as the front washer nozzles did not spray but the rears worked. I thought I would be slick and swap out the plugs on the washer pumps but they are indexed so you can't do that to test if the rears would power the fronts.. Anyways both plugs show 12 volts+..so I assume the front pump has died so I ordered another from Amazon...two day shipping!!

 

Thanks for replying and helping me out but I screwed up royally in not investigating the ICON symbol on the dash as my wifey told me the washer fluid icon is on and the front windshield is not getting sprayed....I took her word and proceeded with bad information.
The ICON was the Defroster ON indicator. I tested voltage to both pumps and they have 12v so I ordered one pump thru Amazon and should arrive today. 2004-2009 have no washer Indicator as their is no sensor in the tank! Thanks again for help irregardless!

 

Just a few technical details I found out with washers pumps on the 2004-2009 Prius. When opening the hood and you are in front of the vehicle looking left....the pump nearest the right front fender is for the rear and next to it toward the engine is the front.
The plug ins are indexed so you can't mixed them up. On mine the rears worked so I thought I would plug the rear plug into the front motor but you can't....had to resort to my DVOM to check for voltage. When ordering pumps the most common one is the front pump plug in configuration.
