Ford F-150/F-250:  Oxygen Sensor Replacement This article walks through the process of replacing the oxygen sensor on your Ford F-150 or Super Duty.  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.

Oxygen Sensor O2 Working Of O2 Sensor in car Maintenance Oxygen sensors are made of reactive materials which limits their lifespan. Aside from mechanical failures such as shorted heating elements or physical damage, these sensors will usually last around 80,000 miles. If an engine has a mechanical failure such as a head gasket (coolant) or an issue that causes oil consumption (rings, valve guides), it will drastically shorten the sensor's life. When replacing your oxygen sensor, be sure to use a high-quality OEM (Original Equipment Manufacturer) part. Cheaper sensors aren't as accurate and don’t last as long as an OEM sensor will, and can cause performance issues as well as emissions problems. Vacuum leaks in the intake system, can give a false the sensor false readings and cause poor engine performance. History As fuel injection evolved, so did the oxygen sensor. Evolving from a one-wire sensor that grounded through the outer case, to a four-wire sensor that grou...
