It’s important to understand what the MAF sensor does. The trouble codes associated with the OBDII scan will reveal which sensor is at fault and why it is bad (at least what the computer thinks is wrong). Or, it may exhibit none at all. What you will need It is smart to use a scan tool to determine whether or not there is an OBDII trouble code associated with any of the sensors. At full throttle, voltage is normally between 4 and 5 volts. Most of the time, the check engine light will come on. Locate the MAF sensor next to the engine air filter housing. Oxygen sensors play a vital role in both engine management and emissions control. This is a list of common symptoms you will notice when your Nissan MAF sensor fails.
The most recently reported issues are listed below. There may or may not be any noticeable symptoms when your Nissan Murano’s oxygen sensor(s) go bad.
The input from the mass airflow sensor is used by your Quest ECU to determine the fuel ratio that the injectors need to deliver to the engine. The good news is, if you end up discovering that the oxygen sensor is bad, they really aren’t that expensive to replace.
Baltimore, Maryland 21224 USA. We will cover exactly what that means and potential fixes for it below. In this guide, you will learn about the Nissan Mass Air Flow (MAF) sensor, a common problem with Nissan MAF, how to diagnose it, replace and carry MAF relearn procedure. For instance, an oxygen sensor at bank 1 – sensor 1 would be: By using a OBDII scanner you can determine exactly which sensor is bad, and what is wrong with it. Without being able to optimize the air fuel ratio, combustion isn’t as efficient, and fuel mileage suffers.
The engine management computer uses the data from all of the O2 sensors to keep the air/fuel mixture optimized. While a rough running engine can be a sign of a bad oxygen sensor, it is often a sign of a misfire as well.

Your Murano can exhibit symptoms when the Oxygen sensor has gone bad. Replacing the MAF sensor on a Nissan vehicle is very easy. In this guide, you will find step-by-step instructions on how to replace the ignition coils on Nissan and Infiniti vehicles 3.5L V6 engine. One of the most common symptoms that an oxygen sensor has gone bad is exhaust that does not smell good. Dirty, obstructed, or faulty mass air flow sensor. © 2020 YOUCANIC a Bohotina LLC company. Since P0101 has to do with the Mass Airflow Sensor, which is a huge part of a computer controlled engine’s combustion process metering. Nissan Murano owners have reported 8 problems related to camshaft position sensor (under the electrical system category).
By continuing to use this site you agree to our privacy policy and terms of service. Locate the diagnostic port under the dashboard, on the driver's side. Nissan MAF sensor is located right next to the engine air filter housing, typically on the driver's side. Allow your scanner to turn on and communicate with the ECU. The hot wire sensors typically have an operating range of 0 - 5 volts. The engine’s computer uses this reading to determine the exact amount of fuel that the engine needs for optimal combustion. In your video it has already been removed , but I need to do it in order to work on the mass air flow sensor. Cleaning the MAF sensor on a Nissan is easy and takes less than 10 minutes. Unplug the mass air flow sensor electrical connector. Your Murano’s oxygen sensors are responsible for helping to keep your engine running at optimal efficiency. This fuel can hurt the catalytic converter. All Rights Reserved. They include: Here are the most common causes of P0101 in the Nissan Murano. Without the proper air/fuel mixture, your engine won’t run as smoothly as it should. Pull the hood release under the dashboard and open the hood of your Nissan.

Sensor 1- Sensor 1 would be the first O2 sensor in the line of sensors starting with the exhaust manifold and making its way back to the exhaust pipe.
Transmission speed sensor on Nissan CVT automa. 2012 Nissan Murano Problems Drivetrain problems and airbag problems plague the 2012 Nissan Murano. If your check engine light is still on, use an OBD2 scanner to clear any stored codes in the ECU. With the Nissan Murano, P0101 means the the Mass Air Flow (MAF) sensor has a Range/Performance problem. It is very rare for there to be a problem with an oxygen sensor, and not have the check engine light come on. Either way, like with rotten food, “the nose knows”. How to Diagnose Nissan MAF Sensor Problems To diagnose the Nissan MAF sensor you will need to read the fault codes stored in the Engine Control Unit (ECU). Install the new MAF on your Nissan. Remove the screws that hold the mass airflow sensor in place.
Here are the most common symptoms of a bad oxygen sensor in your Murano: More often than not, when an oxygen sensor in your Murano goes bad, it will throw a diagnostic trouble code.

As a rule, the upstream sensor is more important for engine timing and air/fuel ratios. Often enough, the only sign of the problem at all is the service engine soon light being on. In this guide, you will find instructions on how to change the Nissan CVT Transmission Speed Sensor. There are many oxygen sensor related codes.
Nissan's mass airflow sensor sends a voltage to the powertrain control module (PCM). The smell is often described as “rotten eggs” or sulfuric. Locate the diagnostic port under the dashboard, on the driver's side. Often enough, there won’t be any noticeable signs of a bad oxygen sensor.
It’s a good thing that the check engine light would come on, as there is more than one oxygen sensor, and they can be difficult to get to and test. Watch the following video on how to remove the air filter box to access the MAF sensor. Write down these codes research them to find out what each code means. Often enough, the only sign of the problem at all is the service engine soon light being on. Oxygen sensors can change the way that your Murano’s engine runs. For this step, you will need an OBD2 scanner. The drivetrain problems are characterized by the transmission not being able to stay engaged in overdriver\, at a speed greater than 60 miles per hour.
