I'm back again with another situation with my demon MK6 GTI. I had the intake manifold replaced a little over 2 years ago. The other day, it threw a CEL and it was a P2015 code. It ran fine aside from not really wanting to go over 45 MPH. The car has a rebuilt title so my local dealership will not replace it under the warranty, plus the dealership breaks something every time the car goes there so that's not an option. The independent shop that did the change only has a 1 year warranty. Is it possible the sensor would just need to be replaced or am I going to need a whole new intake manifold? I would think the revised manifold would last more than 2 years.

Edit: Gonna leave this up, turns out it was just a split vacuum hose on the intake manifold that I overlooked a few times.
