You know that engine function is important to you. You drive a powerful SUV for a reason, and you have no intention of piddling about with anything less than the best. What you also have to remember, however, is that engine function is supremely connected to your exhaust system: the two are entirely intertwined and you can’t consider one without considering the other.

One of the major links between these two systems is your Nissan Pathfinder Oxygen Sensor. The oxygen sensor in your SUV is located near the end of your exhaust system.

Here, it is responsible for measuring the amount of oxygen present in your exhaust vapors. What does it do with this information once it has it? Simple.

You know that your internal combustion engine relies on having the correct air-fuel mixture in order to function smoothly and efficiently, right? And you also know that your engine receives this all-important air-fuel mixture from the fuel injector, correct? Your Nissan Pathfinder Oxygen Sensor is important in that it is the information from this device that informs the fuel injector as to what adjustments must be made to the air-fuel mixture in order to get your engine running at peak performance. Without a great oxygen sensor in your exhaust system, you will never be able to achieve the kind of engine function you desire.Luckily, we have a full selection of Nissan Pathfinder Oxygen Sensors in stock today – so call or order online right now to take a big step towards keeping your engine running in absolute top shape.
