where is the icp sensor located?

04's have it sticking THRU the valve cover on the passenger side...
makes you wonder why they moved it (or who the hell thought it
would be a good idea to put it at the back under everything !?!)

I don't think they moved it for ease of service. They moved it because the heat from the turbo/up pipes was screwing with the sensor. That's why the new updated sensors have a heat-shield attached to them.
