Ensuring a proper oxygen-to-fuel ratio is the job of your Dodge Avenger oxygen sensor. You will find your Avenger oxygen sensor located near your exhaust manifold, directly in the path of the red-hot exhaust leaving your cylinders. Part of a network of sensors that is responsible for measuring oxygen content, your oxygen sensor reads the amount of oxygen in your exhaust and sends the information to your vehicle’s computer hundreds of times per minute.

When there is a problem with your Dodge Avenger oxygen sensor, there can be a number of different consequences, not the least of which is excessive fuel usage. Since your engine relies on the information from your oxygen sensor in order to determine how much fuel should be injected into your cylinders, when the sensor is not working, your vehicle’s computer has to rely on estimates from other sensors that are not located directly in the exhaust stream.

This means your engine will receive too much fuel rather than too little, because an inadequate fuel supply can damage your engine. In addition, the excess fuel running through your exhaust system due to a faulty Avenger oxygen sensor can cause damage to your catalytic converter. Other symptoms of a bad Dodge Avenger oxygen sensor include rough or sluggish engine performance, hot engine running, and black, foul-smelling exhaust smoke. Since it can be difficult to tell whether your Avenger oxygen sensor is working, it is a good idea to replace it at least every 100,000 miles, or whenever you are having exhaust work done.You’ll find the oxygen sensor you need right here in our online catalogue for less.
