Wierd Noise in bottom rear after T4R has been off for hours???

[morphius909]

So tonight I needed to grab something out of the garage, and I heard this weird faint buzzing/electronic whirring noise. I thought it was something outside, but nevertheless I investigated. I couldn't pinpoint whether it was indoors in my garage or outside the garage (door was closed).

Well I bent down near the rear tire of the runner and sure enough it was coming from underneath the truck, almost like the fuel pump was on but much much fainter. I quickly turned the truck on for a few secs and then off and sure enough the sound went away.

So what gives??? The runners been off for at least 6 hours now.

There's a blurb in your manual about it. SOme NORMAL electronic gizmo venting something I think. No worry.

It's in the owner's manual. It's evap system purging or something along those lines. It happens about 6 hours after the engine's been shut off.
