The standard 2.5L 4Cylinder motor will have three oxygen sensors total. The upgraded 4.0L V6 engine is going to have a total of four oxygen sensors on the vehicle. No matter which model You have they will both have two on the catalytic converter. If You need to replace a fault o2 sensor it won’t cost too much.

Where is the oxygen sensor on a 2004 Nissan Maxima?
Upstream sensor (located before catalytic converter).
Where is the O2 sensor located on a Nissan Maxima?
Your Nissan will have at least two oxygen sensors. One O2 sensor is upstream (Bank1-Sensor1 ) of the catalytic converter and can be accessed from the top of the engine.13 avr. 2021
How many sensors does a 2004 Altima have?
A vehicle may have two to five oxygen sensors, and sometimes even more. 2002-2004 Nissan Altima with 3.5 Engine O2 Sensor Location.1 fév. 2020
Can you drive with a bad o2 sensor?
Can You Drive With A Bad Oxygen Sensor? Yes, you can drive with a bad oxygen sensor if you can still start your engine and feel little difficulty driving. But don’t leave it alone for over a couple of days, as it might cause safety problems and lead to the malfunction of other parts of your vehicle.27 nov. 2020
How can you tell which o2 sensor is bad?
1. Reduced gas mileage.
2. A bad smell like rotten eggs coming from the exhaust.
3. The check engine light comes on.
4. You notice that your engine idles roughly.
5. The car is suddenly hard to start.
Is bank 1 sensor 1 upstream or downstream?
Bank 1 Sensor 1 means Upstream Right/Rear;Bank 2 Sensor 1 means Upstream Left/Front;Bank 1 Sensor 2 means Downstream Right/Rear;Bank 2 Sensor 2 means Downstream Left/Front.
Is Bank 1 sensor 1 Left or right?
Bank 1 Sensor 1 is located right before the catalytic converter.4 déc. 2020
Which is bank 2 sensor 2?
Bank 2 is the set of cylinders that does not have number one cylinder. Sensor 1 is the sensor before the catalytic converter which the computer uses to make fuel ratio calculations. Sensor 2 is the sensor that comes after the catalytic converter and is mainly used for onboard emissions testing.29 mar. 2016
How can you tell the difference between an upstream and downstream oxygen sensor?
The upstream oxygen sensor is situated before the catalytic converter whereas the downstream oxygen sensor is located after the catalytic converter. The upstream sensor monitors the level of pollutants in the engine’s exhaust and sends this information to the ECU that continuously adjusts the air-fuel ratio.30 avr. 2019
Where are my O2 sensors located?
The Oxygen O2 sensor is located in your vehicle’s exhaust system, usually on the exhaust manifold or close to the engine. There may be several oxygen sensors on your vehicle. These sensors are always located in the exhaust gas flow of your vehicle.
What does code P015A mean?
When an OBD-II equipped vehicle has a stored P015A code, it means that the powertrain control module (PCM) has detected a delayed response time from the upstream (first one after the exhaust leaves the engine, in front of catalytic converter) oxygen (O2) sensor or circuit for engine bank one.
How many O2 sensors does a 2003 Nissan Altima have?
There are 2 sensor. A vehicle may have two to five oxygen sensors, and sometimes even more. 2002-2004 Nissan Altima with 3.5 Engine O2 Sensor Location.20 mar. 2020
What is an air fuel ratio sensor?
The air-fuel ratio sensor monitors the oxygen content in the exhaust stream and sends data to the computer so that it can add or subtract fuel. If there is any problem with the sensor, it can send a bad or false signal to the computer which can throw off its calculations and cause it to waste fuel excessively.4 jan. 2016
How many O2 sensors does a 05 Nissan Altima have?
Many thanks upfront! Only 2 O2 sensors… Both can be seen from the top of the engine, looking down at the exhaust manifold/precat.2 déc. 2008
