At a time when gas prices never seem to stop rising and the quality of our environment never seems to stop degrading, many people exhaust all means just to find a more affordable, more efficient and more environment friendly source of vehicle power. Much to the unawareness of many, however, fuel economy and safer vehicle exhaust emissions can readily be achieved without even touching on the fuel used on vehicles! If a proper mixture of air and fuel is constantly fed on the vehicle's engine, much of this mixture will be converted to mechanical energy, thus increasing engine efficiency, improving fuel economy and reducing harmful emissions. But is there a way for this proper mixture to be achieved?

Well, there actually is and the technology has been around since the 1980s. In fact, all gasoline-powered vehicles manufactured since 1980-1981 are equipped with a vehicle component called oxygen sensor. Oxygen sensors are small sensors inserted in the exhaust system of gasoline-powered vehicles to measure the volume of oxygen remaining in the exhaust gas. This volumetric information is then transmitted to the engine's electronic control unit (ECU) computer. With the said information, the computer can determine whether the mixture fed to the engine is rich (too much fuel) or lean (too little fuel). The ECU then makes adjustments so that the proper mixture would be achieved.

Many Ford vehicles were produced long before automotive O2 sensors were invented, so there are definitely a lot of Ford vehicles that cannot use the technology. However, if your Ford was manufactured after 1980, you can be assured that they are equipped with Ford oxygen sensors. Ford vehicles manufactured prior to 1996 are expected to be equipped with one or two oxygen sensors that can be found on the exhaust manifold. In 1996, after the use of on-board diagnostic systems (ODB-II) on vehicles was mandated by law, additional oxygen sensors installed after the catalytic converter also became standard.

Now, if your Ford is fairly new, there's no doubt that it is equipped with Ford oxygen sensors. The question now is whether the sensor is still working properly. Unfortunately, there is no way to immediately tell if your Ford's oxygen sensor is already damaged or is working poorly; not until it fails an emissions test, a decline in fuel economy is noticed, or worse, if various parts of the engine and the catalytic converter have also been damaged. This is the reason why many automotive experts would recommend that the oxygen sensor be replaced, or at least checked, regularly.

So, is it already time for you to replace your Ford's oxygen sensor? Then you better get yours from a reliable online auto parts source like Parts Train. Here at Parts Train, we have all sorts of Ford oxygen sensors (unheated thimble, heated thimble, planar, wideband and titania) for all applicable Ford vehicle years and models. And because you can easily locate us through the net, the hassles of actually lining up on the counter would greatly be avoided.
