The first Ford "F-Series" pickup rolled off the Dearborn assembly line all the way back in 1948 - when it was known as the Ford "Bonus." Oxygen sensors were not even invented back then, and weren't installed until the late 1970's. In the old days when gasoline was cheap and plentiful, most people didn't think about where it all came from and where it went to after exiting their tailpipes.. Today's Ford F250 (early 1980's - present) has changed with the times.

Now that fuel economy is on a lot more people's minds, the Ford F250 Oxygen Sensor has become a vital part of the exhaust system, allowing it to work with the fuel system to reduce fuel consumption and emission control. There is an optimum fuel-to- air ratio, or "mixture," that keeps the engine to running at peak performance while minimizing fuel costs and exhaust emissions.

When the mixture is leaner (more air and less fuel), less exhaust is produced. A Ford F250 Oxygen Sensor measures oxygen content in exhaust gases, then sends an electronic signal to the fuel injection system, which adjusts the fuel mixture accordingly. When damaged or defective, an oxygen sensor cannot perform this function, lowering engine performance. Fuel consumption and polluting exhaust will also result. Get rid of that defective oxygen sensor and replace it with a genuine Ford F250 Oxygen Sensor today.
