The Mazda 6 oxygen sensor monitors the exhaust system, specifically managing the expended gases. On a Mazda 6, and most other cars, the oxygen sensor can generally be found on the header pipe, sometimes varying between years and models. The job of the oxygen sensor is to keep track of the fuel mixture in your engine, ascertaining whether it contains too much fuel (which is labeled rich) or too much oxygen (referred to as lean). Next, the electronic fuel injector sensor communicates to your vehicle and will adjust the amount of either fuel or oxygen, depending upon the current circumstances mixture according to the conditions which will adjust depending upon varying altitude and ambient temperature. When an oxygen sensor malfunctions, it can dump fuel and cause the vehicle to begin emitting black smoke from the exhaust pipe. This indicates an overabundance of fuel and not enough air. The task of removing the old oxygen sensor is not difficult, as the sensor is usually viewable on the exhaust header. An open-end or box wrench will do the job of taking off the sensor. Then just unplug the wire from the old oxygen sensor (this is imperative, otherwise you could damage the wire) and then simply screw the new sensor in and plug the wire in.

Research on Oxygen Sensor for Mazda 6

Detecting oxygen in the exhaust is a critical job for your engine to run properly. When one of your Mazda 6's oxygen sensors fails, you'll experience numerous problems with your car's operation and performance. Though a faulty oxygen sensor can make your engine run less efficiently, it does not have to ruin your day.

What is the Oxygen Sensor and What Does It Do?

The oxygen sensors, also sometimes called O2 sensors, are part of the exhaust on your Mazda 6. Your 2006 Mazda 6 oxygen sensor location and number depends on your engine type. Usually, you have one on either side if you've got a 6-cylinder or larger engine, but for smaller 4-cylinder engines, you only have a single O2 sensor. The oxygen sensors on your Mazda 6 are designed to measure the oxygen levels in the exhaust. These levels are used by the engine's computer to make changes to the air and fuel levels in the engine. Usually, Mazda 6 oxygen sensor problems will cause problems with your air-to-fuel ratio. You may also have other issues with your car's performance when one of your oxygen sensors goes bad.

When Should an Oxygen Sensor Be Replaced?

Oxygen sensors are plug in parts that don't require a lot of effort to replace, but they will wear out over time or become clogged. Most often, other issues with your engine or exhaust will cause damage to the oxygen sensor, necessitating its replacement. When the oxygen sensor goes bad, you may find that your fuel economy on your Mazda takes a dip. The engine likely idles roughly or misfires, and your check engine light will come on. These are signs that you should consider a replacement for your O2 sensor, or sensors, depending on your Mazda's engine size.

Why an O2 Trouble Code May Not Mean a Bad Oxygen Sensor

Keep in mind, though, that a check engine light and a trouble code for a bad oxygen sensor could indicate that there is another problem in the exhaust system, such as a leaking pipe. If your oxygen sensor has been recently replaced and you are still getting a trouble code for it, you may not have a bad O2 sensor but a leak in your exhaust system.

Mazda 6 O2 Sensor Replacement Cost

The cost for a new oxygen sensor is lower than other part replacements because the labor costs are comparatively low and so are the parts, but you could still spend anywhere from $163 to $330 for a mechanic to install a single 2010 Mazda 6 O2 sensor on a 4-cylinder engine. You will spend more if you have to replace two oxygen sensors on a 6-cylinder engine, and your model year may also make a difference in the final price as does the usual labor costs your mechanic charges for this service.

How to Save Money on a New O2 Sensor

Because the oxygen sensor just plugs into place, you'll likely be able to replace it yourself as long as you can reach it. This will save you money on the replacement cost. Shopping at PartsGeek.com for your Mazda 6 oxygen sensors will also help you to spend a lot less and restore your Mazda 6's power.
