My nearly perfect 2007 Frontier is starting to emit a loud, high-pitched buzzing whine. It seems to be independent of engine speed. It turns on and off. It actually sounds like the fuel pump on my old GMC truck, a flanging piezo buzzer sound, but those don't turn off on the GMC.
What could it be?
It's a 2007 Frontier LE 4x4 crew cab, short bed, 4.0 V6, with no off-road bits.
