Hey guys, I have a 2001 is300, and I recently heard a hissing sound from what sounds like the rear wheel on the driver side. I also have a p0440 check engine light that has to do with emissions control and thought they could be related, because the code says its a loss/leakage of pressure. Any thoughts?

Could be a bad hose by the VSV. There's some videos that show how to change it out; it doesn't look like fun to replace.

Here's the link:
Good Luck.
