A faulty O2 sensor is the major cause of car issues, including low mileage, stalling engine, and overall performance. Fixing the problems becomes easier when you know the number and location of the O2 sensors.
So, how many O2 sensors does a Nissan Murano have? Total 4 O2 sensors – 2 of them are on the catalytic converter, and 2 others are on the cylinder bank.
That’s the number of O2 sensors on the Nissan Murano. But the full story remains with much more information. You’ll get the importance and common symptoms of bad O2 sensors there.
Therefore, the entire post is worth reading regarding the O2 sensors.
Let’s proceed to the next scene!
How Many O2 Sensors Does A Nissan Murano Have With Features
We revealed in the intro the number of the Nissan Murano oxygen sensor. If you own the Nissan Murano, it's vital that it has four O2 sensors.
Before we enter into the next scene, here is a table of the O2 sensors of different models and years with their locations:
| Year | Model | Total Sensors | Sensor Location |
| 2003 | Nissan Murano | 4 | 2 on the manifold three-way catalyst 2 on the cylinder banks |
| 2004 | Nissan Murano | 4 | 2 on the manifold three-way catalyst 2 on the cylinder banks |
| 2005 | Nissan Murano | 4 | 2 on the manifold three-way catalyst 2 on the cylinder banks |
| 2006 | Nissan Murano | 2 | 2 on the manifold three-way catalyst |
| 2007 | Nissan Murano | 4 | 2 on the manifold three-way catalyst 2 on the cylinder banks |
| 2008 | Nissan Murano | 4 | 2 on the manifold three-way catalyst 2 on the cylinder banks |
| 2009 | Nissan Murano | 4 | 2 on the manifold three-way catalyst 2 on the cylinder banks |
| 2010 | Nissan Murano | 4 | 2 on the manifold three-way catalyst 2 on the cylinder banks |
| 2011 | Nissan Murano | 4 | 2 on the manifold three-way catalyst 2 on the cylinder banks |
| 2012 | Nissan Murano | 4 | 2 on the manifold three-way catalyst 2 on the cylinder banks |
| 2013 | Nissan Murano | 4 | 2 on the manifold three-way catalyst 2 on the cylinder banks |
| 2014 | Nissan Murano | 4 | 2 on the manifold three-way catalyst 2 on the cylinder banks |
Let's Discuss: How Many O2 Sensors Does A Nissan Murano Have?
Let’s start with the following: how many O2 sensors does a 2006 Nissan Murano have? Truly, it has two O2 sensors. Many users often mistakenly think it has four oxygen sensors.
The two sensors on the upper side of a 2006 Nissan Murano aren’t O2 sensors. Even they act like and look like standard oxygen sensors. Indeed, they’re Air Fuel Ratio sensors.
Except for a 2006 Nissan Murano, all other models, such as the oxygen sensor Nissan Murano 2009, 4 in total. So, if you’re a 2006 Nissan Murano owner, you must remember that your car has two O2 sensors, unlike other Nissan Murano models.
When it comes to a 2004 Nissan Murano, you may want to know: how many oxygen sensors does a 2004 Nissan Murano have? The answer is four sensors because the manufacturer maintained the same configuration to produce all cars of the Murano series.
Some other users may own a 2007 Nissan Murano. They usually ask to know: how many oxygen sensors does a 2007 Nissan Murano have? Although the models are different, the number of the O2 sensors is the same – four.
Nissan Murano O2 Sensor Locations
When you need to find out a 2009 Nissan Murano O2 sensor location, you’ll get it on the manifold three-way catalyst. As you learned where the O2 sensors locate, you can fix any issue with them without difficulty.
Also, it’s the same as a 2005 Nissan Murano O2 sensor location. The latest vehicles, like Nissan Murano, have been designed with two plus two, equal to four oxygen sensors.
Likewise, 2005 and 2009, a 2012 Nissan Murano O2 sensor also resides at the manifold
catalyst. You might have noted that all years of Nissan Murano O2 sensors come with the same locations.
So, you’re all set about a 2009 Nissan Murano oxygen sensor location and all other car years of the Nissan Murano series. Let’s move to the next scene…
Why Do The O2/Oxygen Sensors Important?
O2 sensors are vital for a car to control its internal pollution. The engine control module (ECM) gets and modifies data on oxygen in the gases. It also helps the system to regulate the air and fuel ratio.
O2 sensors do not just decrease pollution; they also boost fuel efficiency. As a result, you get the best engine performance. Otherwise, you need more fuel to drive the cars, and they’ll produce more contaminants.
What Are The Symptoms Of The Bad Oxygen Sensors?
Several issues may happen to a defective O2 sensor. Here are some of the common symptoms of bad O2 sensors with their potential fixes:
| Symptoms | Solutions |
| Flashing CEL (Check Engine Light) | Replace concerned O2 sensors |
| Lower fuel efficiency | Replace concerned O2 sensors |
| Poor engine performance | Replace concerned O2 sensors |
| Rough idle, misfires, stalling | Replace concerned O2 sensors |
| Higher emission rates | Replace concerned O2 sensors |
| Exhaust fumes become blacker | Replace concerned O2 sensors |
| Bad odor from the exhaust | Replace concerned O2 sensors |
| Catalytic converter fails unexpectedly | Replace concerned O2 sensors |
| Engine overheating | Replace concerned O2 sensors |
Frequently Asked Questions – FAQs From People Also Ask
Do I Need To Replace All Four Oxygen Sensors All Together?
Replacing the O2 sensors in pairs is recommended. For instance, when the left O2 becomes faulty, it’s best to replace it with the right one, even if that one is working well. Keeping one old and one new O2 sensor can unstable the engine control system.
Do All Nissan Murano Years Have The Equal O2 Sensors?
Yes, for all, except the 2006 Nissan Murano. It means all vehicles of the Nissan Murano series come with four O2 sensors without 2006. Only a 2006 Nissan Murano has two oxygen sensors.
How Much Does It Cost To Replace A Nissan Murano Sensor?
It might be a 2010 Nissan Murano oxygen sensor or any other model of the Murano series; the average replacement cost ranges from $376 to $410. The costs include labor and parts.
Can I Drive My Car With Damaged O2 Sensors?
You should avoid driving your car with bad O2 sensors. If you drive a car with defective oxygen sensors, it’ll consume more fuel than it regularly does. Also, it’ll produce more emission with lower engine performance.
How Long Does An O2 Sensor Work Well?
Usually, an oxygen sensor provides the best service between 30,000 and 50,000 miles. They’re highly durable even in excessive heat, toxic gases, and higher velocity.
Does Replacing Oxygen Sensor Impact Engine Performance?
When an oxygen sensor malfunctions, it can impact the engine's performance. It may happen even if you change with a new sensor by an inexperienced mechanic.
The Bottom Line
That’s all about the answer to your question: how many O2 sensors does a Nissan Murano have? This post taught us about all Nissan Murano models and years of oxygen sensors. It includes the total number of O2 sensors and their locations.
Moreover, you got essential information regarding the bad O2 sensors with their possible fixes. Also, you learned the replacement cost of a malfunctioning oxygen sensor.
But never ignore the warning signs/symptoms of bad O2 sensors. Whenever they become visible, take necessary actions immediately to avoid further engine damage.
