Where are the oxygen sensors on a Nissan?
Your Nissan will have at least two oxygen sensors. One O2 sensor is upstream ( Bank 1- Sensor1 ) of the catalytic converter and can be accessed from the top of the engine. One or two sensors will be downstream, B1S2 and B2S2. The procedure is similar for the downstream O2 sensors (Bank 1 & 2, Sensor 2).

Please narrow the Oxygen O2 Sensor results by selecting the vehicle. One of the heat-resistant components working on your Nissan is your oxygen sensor, and every one of them is engineered to withstand very high temperatures for many years.
What happens if your O2 sensor is bad?
Sudden decrease in fuel mileage. A defective O2 sensor will likely cause your air-fuel mixture to be too rich and directly affect your fuel economy. Flashing check engine light or malfunction indicator lamp in the vehicle?s dash board. Of course this can happen for other reasons as well (and a defective oxygen sensor is one of them!)
What happens when your O2 sensor goes bad?
When an O2 (oxygen) sensor go bad, it’ll cause your Nissan Altima ‘s engine to run less efficiently. Your Altima can exhibit symptoms when the Oxygen sensor has gone bad.
Can a Nissan Altima oxygen sensor go bad?
In this video I replace the upstream oxygen sensor replacement on my 1999 Nissan Altima. When oxygen sensors go bad it can cause the engine to run bad or die. Sometimes it’s very hard to find that the oxygen sensor is at fault because it might not log any faults for that.
Can a bad oxygen sensor cause a car to fail an emissions test?
Often enough, there won’t be any noticeable signs of a bad oxygen sensor. You’ll go to get an emissions check done, and your Altima fails the test. Without a check engine light, it can be tough to lock down exactly what would cause the vehicle to fail, but oxygen sensors are one of the more common causes.
When do you need to replace your oxygen sensor?
Oxygen sensors eventually need to be replaced in all vehicles. If your vehicle’s O2 sensor is faulty, chances are there will be signs! Check this list to see if it’s time to replace YOUR vehicle’s oxygen sensors:
What to do when your oxygen sensor fails?
When the oxygen sensor fails on your Quest, you may notice some or all of the following issues: Park your Nissan Quest and open the hood. Your browser does not support the video tag. Disconnect the negative battery terminal. Locate the oxygen sensor on your Nissan Quest.
Where can I buy an oxygen sensor for my Nissan Pathfinder?
The oxygen sensors can be purchased from the dealership if you want OEM parts, or they are also available from any auto parts store as aftermarket replacement parts. Raise the front of the truck with a jack and support it with jack stands placed under the frame.
Where is the mass air flow sensor on a Nissan?
Locate a mass airflow sensor in the engine bay. Nissan MAF sensor is located right next to the engine air filter housing, typically on the driver’s side. Unplug the electrical connector from your Nissan mass airflow sensor. Watch the following video on how to remove the air filter box to access the MAF sensor.
What’s the best way to remove an oxygen sensor?
Unscrew the oxygen sensor off the exhaust pipe using either an open-end wrench or a special socket made to remove it. The majority of oxygen sensors will take an SAE 7⁄8 inch (2.2 cm) wrench.
When to reset the ECU after changing an O2 sensor?
Sometimes an O2 sensor fails, and you need to replace it. Once you’ve replaced your vehicle’s O2 sensor, you’ll need to reset the ECU so it can properly gather information from the new O2 sensor.
What are the downstream O2 sensors on a Nissan?
One or two sensors will be downstream, B1S2 and B2S2. The procedure is similar for the downstream O2 sensors (Bank 1 & 2, Sensor 2). For the downstream sensors, you will find it easier to access the O2 sensor from underneath the car.
How do you remove the oxygen sensor from a Nissan?
The downstream oxygen Bank 1 Sensor 2 sensor has to be accessed from underneath the engine. You will need to remove the bottom splash shield. Disconnect the oxygen sensor electrical connectors. Press the connector and pull it away to unplug it from the oxygen sensor. Use an oxygen sensor wrench to remove the oxygen sensor.
The downstream oxygen Bank 1 Sensor 2 sensor has to be accessed from underneath the engine. You will need to remove the bottom splash shield. Disconnect the oxygen sensor electrical connectors.
When does an O2 sensor set a trouble code?
If it’s not switching rapidly, the ECM will set an O2 sensor related trouble code If the upstream and downstream oxygens sensors are both switching from rich to lean, that’s the sign of a dead catalytic converter. An exhaust system leak really screws up the P0420 testing routing.
What to do if your O2 sensor is not working?
If the voltmeter does not respond, the o2 sensor is not functioning properly. Reconnect the PVC hose to test the o2 sensor’s response to a rich fuel consumption situation. To do this disconnect the plastic hose connection to the air cleaner assembly.
How many O2 sensors are in a car?
If a vehicle being serviced is not covered in the charts, inspect the exhaust system in the general locations to find the applicable O2 sensors. NOTE: If equipped with dual exhaust systems, there may be up to 4 or 5 O2 sensors in the exhaust system. Be sure to locate all of them before commencing with any testing or service.

Why does my Nissan Rogue have a bad O2 sensor?
When one cylinder did not fire, it was dumping that fuel out the exhaust which could have caused “P0430 NISSAN – Catalyst System Efficiency below Threshold Bank 2”. The other three fault codes P1288, P1168 and P1283 could all be attributed to the bad O2 sensor.
Can a bad O2 sensor cause a misfire?
Suggestions I received ranged from switching or replacing ignition coils, checking the air intake for leaks, or cleaning the MAF (Mass Air Flow) sensor, to checking for ECM (Engine Control Module) problems, among many more. The possibility that it would be a bad ECM was a little unsettling, because of the potential cost of replacing it.
Where is the fault code on the O2 sensor?
The fault code P1288 identifies the O2 sensor location as sensor 1, bank 2, otherwise known as the front or upstream sensor on the passenger side of the vehicle. To learn the difference between the upstream and downstream O2 sensor, check out the video below.
What happens when the oxygen sensor goes bad in a Nissan Frontier?
More often than not, when an oxygen sensor in your Frontier goes bad, it will throw a diagnostic trouble code. There are many oxygen sensor related codes. These codes correspond with what side of the engine they are on (known as the “bank” for cylinder bank) and how far down stream they are.
Why does the Check Engine light come on on my Nissan Frontier?
Oxygen sensors can change the way that your Frontier’s engine runs. Most of the time, the check engine light will come on. 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.
