Ford F-150 (2004-2014) and the F-250, F-350 (2005-2014).
If your check engine light goes on but you don't notice any symptoms, you need to use a code reader to determine the source of the problem. If the trouble code in your PCM's memory reads P0131, P0133, P0151, or P0153, you could be having trouble with your vehicle's oxygen sensor. The oxygen sensor is a clever little component that keeps track of your engine's exhaust and promotes an accurate distribution of oxygen, nitrogen, and fuel. For this reason, bad gas mileage can be both a symptom and a problematic result of a faulty oxygen sensor. This part can be expensive to professionally replace, so you might want to attempt a DIY job if you are able to.
