The 2011 Ford F-150 3 5 EcoBoost oxygen sensor location is along the intake manifold. There are actually a couple of them along the way. The sensor is in charge of making sure that the car has the correct air to fuel mixture. If it does not then it will be running either rich or lean, which means that the car does not have the proper engine setup and could lead to damage in the long term. In the short term, You may notice a lack of power or bad fuel mileage. If this is the case You should get the sensors replaced. They are cheap, about 40 to 60 dollars each, so it should not big deal to get this done.
