A check engine light, lower fuel economy or a rough idle can mean an oxygen sensor is wearing out. These signs alone do not show the sensor is the problem, since a vacuum leak can also bring on a rough idle and a warning light. This listing is one sensor; how many a vehicle takes depends on the engine, and the 2001-2008 Ford F-150 V8 5.4L takes two.
