Jeep Oxygen Sensor

Jeep vehicles, despite their very contemporary appearance, except maybe for the Jeep Wrangler, are conventional SUVs at their very core. On the positive side, that means that these truck-based sport/utility vehicles are capable of traversing even the roughest of paths. On the negative side, however, this means that owning a Jeep is almost synonymous to owning a gasoline-drinking monster! This is not to say that there is no way for you to minimize the fuel consumption of your Jeep. In fact, you can maintain the fuel consumption of your Jeep at its lowest, but only if the Jeep oxygen sensor is properly taken care of.

The Jeep oxygen sensor is a small sensor inserted into the exhaust system of gasoline-powered Jeep engines that is designed to measure the amount of remaining oxygen in the exhaust gas. The data gathered by the O2 sensor would then be transmitted to the engine's electronic control unit (ECU) computer which analyzes whether the oxygen volume indicates a rich (too much fuel) or lean (too little fuel) mixture of air and fuel in the cylinders. Based on this analysis, the engine management computer then adjusts the air/fuel mixture to be fed to the engine.

If the proper mixture of air and fuel, or something close to that mixture ratio, is constantly fed to the vehicle's engine, much of the fuel consumed by the engine is converted into mechanical energy. This would result to maximized fuel economy and reduction in harmful exhaust emissions. This condition, however, can only be achieved if the oxygen sensor of your Jeep is working properly. Unluckily, O2 sensors deteriorate with age. In due time, contaminants from normal combustion and oil ash would accumulate on the actual sensor, reducing its capability to properly measure exhaust gas oxygen levels.

In most cases, damages in the various parts of a vehicle would let themselves be felt by the driver. This, however, does not apply to oxygen sensors. There's no way that any one can instantly notice the failure of oxygen sensors because the change in performance occurs gradually. You may not even notice that the oxygen sensor is no longer functional until your Jeep fails an emission test. And during that time, a lot of other components in your engine and exhaust system, especially the catalytic converter, must have already incurred a lot of damages.

So how can you determine if your Jeep's oxygen sensor is already damaged and already needs to be replaced? Unluckily, again, there's no easy way to do that. Regular visits to auto repair shops may be the only possible way. Some automotive experts would recommend replacing the O2 sensor after a particular vehicle mileage has been reached. You may check on your Jeep's manual if the manufacturer recommends something like that. Then if its time to replace your Jeep oxygen sensor, you know who to trust – Parts Train.
