Jeep oxygen sensor is the device that significantly measures the amount of oxygen in the exhaust, converts its status into a corresponding voltage signal and sends this voltage signal into a computer in the vehicle. The computer will then issue a command to the fuel injector to adjust and maintain the proper air/fuel ratio. Jeep oxygen sensor needs to check this red-hot exhaust hundreds of times per minute to make sure that it gets a correct data which will be forwarded to a computer in the vehicle.
Having such a critical job, your Jeep oxygen sensor needs to be taken-cared of and maintained properly. As they become older, Jeep oxygen sensors can turn out to be inaccurate, leading to waste of fuel and some engine performance problems. So if you notice that your Jeep oxygen sensor is poorly operating, better replace it immediately to avoid further damage as well as fuel inefficiency.
And to avoid constant replacement of your Jeep oxygen sensor, make sure to check it when you conduct a routine vehicle tune-up. Remember that checking your Jeep oxygen sensor is as important as changing your vehicle's oil, checking the spark plugs and replacing the air filter.
