I have been looking at this thing for a while now, and I want to know what it is for.



I haven't bothered running any tests on it yet. Not that it would likely do any good, I have an SV and that means I don't have much more than heat and a radio on my car.

This is from an 08 aveo5 SV it's in the engine bay to the side of the cooling fan, under and behind the radiator.
