I have a common issue which is a leaky washer fluid tank. I have tried to fix it 3 times now, bought all the bushings I could find and even used sealing caulk on some of the non bushing connections. It still leaks and I don't mind.
But what really annoys me is the constant warning in my dash cluster. Has anyone ever jumpered this sensor?
Do you think you could just unplug the sensor and jumper the two connections in the plug and never get this warning again?
It is possible that would work, but there also is a possibility that the sensor reads capacitance and not resistance.
If you want to find out you could follow this method. (copied from another forum).
So over the weekend my buddy and i pulled the "sensor" out of the washer fluid tank and we started poking & prodding at it with his super fancy fluke multi-meter. Initially we figured it'd go by resistance, we put the prongs of the sensor in a dish of water and got 1.5 megaohms IIRC. So we fastened the appropriate resistor to the prongs and hooked it back up to the truck to see what would happen, and it didn't work at all, as soon as the truck was turned on within seconds the low washer fluid light came on.
So next we tested capacitance. Embarrassingly enough, I was actually out of washer fluid so we were testing with water, water yielded a capacitance of 1.5 uf or Microfarads, we were able to locally find a 1uf electrolyte capacitor, which wasn't ideal but, we put the leads into the harness and tested it it out, and sure enough inserting the capacitor into the harness would make the Washer fluid Low error go away after a minute or so, removing it would make it come right back, so we had our answer. After the fact, we got some washer fluid and tested the capacitance of the washer fluid to be 560nf, so we feel any capacitance between the 560nf of washer fluid & the 1.5uf of water should work just fine.
