Bank 1 is the side with the #1 cylinder, while bank 2 is the side with the #2 cylinder, as stated by Towncivilian. So, bank 1 is the passenger side and bank 2 is the driver’s side.
The O2 sensor harness connector locations are listed below to help with diagnosis:
So why is the car throwing a code for bank 1 sensor 2 if I deleted bank 1 sensor 1?

I persuaded my husband’s workplace to scan the error code after my Pathfinder stalled on the road the other day. I assumed it was the camsensor, and sure enough, error number p0340 Cam bank 1 was shown.
I have a 2005 SE Off-road 4WD Pathfinder. However, I’m presuming that the component will fit all 2005 Pathfinder models.
In order to substitute bank 2, I’ve discovered films and what not, but not bank 1. Is it the same component? Do I need a curved one instead? I’m aware that bank 2 is slightly skewed.
The right bank (or passenger side in North America) cylinder head’s rear houses the bank 1 cam sensor. Getting to it is a little difficult. One bolt with a 10MM head will be used to secure it. Since aftermarkets have been troublesome, I advise sticking with authentic Nissan parts. If you insist on pursuing the aftermarket route, I would choose the Hitachi out of the components displayed where you are purchasing. The sensor should be of the same caliber as Hitachi is Nissan’s original equipment manufacturer’s supplier.
On the right, the passenger side, is Bank 1. On the back of the head, it is situated. That sensor has a straight connector, after all. It can be challenging to release the connector.
How to Examine a Nissan Pathfinder’s Oxygen Sensor
As a fuel mixture indication, the oxygen sensor counts the amount of free oxygen in the exhaust system. The ideal fuel mixture for combustion and emission management is 14.5:1. When it comes into contact with oxygen, it generates a voltage in the millivolt range. When the computer detects this signal, it modifies the injectors’ on-time to account for it. A Nissan Pathfinder has at least two oxygen sensors, one in front of and one behind the catalytic converter. This is done in order to gauge both the amount of pollutants produced by the converter and the amount of unburned fuel entering it.
Which side of a 2005 Nissan Pathfinder is bank 2?
Fits all 4.0L V6-powered Pathfinder models built from 2005 to 2012 for bank 2 or the left side (driver side). The ease of exchange with OEM units and correct fit are guaranteed by direct fit units.
Is bank 2 on the front or rear?
Each car has a different version of where Bank 2 is. Depending on the vehicle’s make, model, and driver orientation (left-hand or right-hand drive). To merely state that it is located on the passenger side would be presumptuous (although this is predominantly true for rear-wheel drive). The side of an engine having the cylinder firing orders 2, 4, 6, 8, 10, and 12 is referred to as Bank 2 by definition. The B1S1 (Bank 1 Sensor 1) placement is opposite of this.
You can fairly well pinpoint the position of Bank 2 by locating Cylinder 2. Finding Bank 2 in front-wheel drive cars is more challenging than in rear-wheel drive cars, though. It is crucial to identify the engine’s “front side,” or the area nearest to the crankshaft pulley. Although the “front side” is typically closer to the glass than the radiator, not all front-wheel-drive automobiles will have this configuration.
Which bank on an engine is bank 1?
In the world of automobiles, Bank 1 refers to the bank with the first cylinder, i.e., it is the bank with the first cylinder. This is the sole cylinder bank on an inline four-cylinder engine. On an inline six-cylinder engine, two banks could appear in the scan tool data even if there is only one real cylinder bank in practice.
The BMW M54 engine, which uses two distinct exhaust manifolds in a single-cylinder bank arrangement, is a good illustration of this. Bank 1 refers to the front three cylinders of the M54, which house the number one cylinder.
Likewise, Bank 2 refers to the back three cylinders. The rule is the same for engines with opposed cylinder banks, like a V8 engine, in that bank one is always the bank with the first cylinder. To learn the cylinder arrangement for a certain engine, consult the service manual.
Where are banks 1 and 2 situated?
Simply put, banks 1 and 2 refer to the engine’s sides. For accurate information on where banks 1 and 2 are located, consult your owner’s manual or a service manual. Most frequently, bank 1 houses the first cylinder from the front of the engine, and bank 2 is the opposite side. View numerous potential setups in the images below.
Tech Tip: The area of the engine closest to the front of the car is not the front. That side has a crankshaft pulley on it (also called the harmonic balancer). No matter how the car is set up, whether it has front- or rear-wheel drive, or where the engine is located.
Typically, the appropriate O2 sensors can be found in each of these banks. Only one bank is present in 4 cylinder engines, with some Subarus being an exception. There is just one bank available, so bank 1 should be chosen when you notice codes that frequently refer to bank 1.

Which bank is on the left side of the engine?
The front bank is another name for the left cylinder bank. It’s cylinders 2, 4, and 6. The radiator is located closest to the left bank. The rear bank is another name for the right cylinder bank.
Which comes first, the catalytic converter or bank 1?
Each car has a different number of O2 sensors, although all cars have at least two.
This is due to the fact that each car contains a minimum of one downstream and one upstream oxygen sensor (sensor 1). (sensor 2).
While sensor 2 is placed after the catalytic converter, sensor 1 is placed before it.
By reading the diagnostic trouble code (DTC) and identifying the appropriate bank in accordance with the previous instructions, you can identify the malfunctioning O2 sensor when reading a DTC.
A DTC that reads “Bank 1 sensor 2,” for instance, indicates that the O2 sensor is situated next to cylinder 1 after the catalytic converter.
The O2 sensor, on the other hand, is situated before the catalytic converter, on the same side as cylinder 1, according to a DTC that states “Bank 1 sensor 1,” on the other hand.
The O2 sensor is situated on the other side of bank 1 after the catalytic converter, according to the same reasoning, therefore “Bank 2 sensor 2” would show this location.
Are sensors 1 from banks 1 and 2 identical?
Bank 1 The first sensor, which is closest to the engine, is Sensor 1. On Bank 1 denotes that the cylinders 1, 3, 5, 7, etc. are on the engine side.
The second sensor on the engine’s exhaust pipe, often located after the catalytic converter, is known as Bank 1 Sensor 2. On Bank 1 denotes that the cylinders 1, 3, 5, 7, etc. are on the engine side.
The first sensor nearest to the engine is Bank 2 Sensor 1. On Bank 2 denotes that the cylinders 2, 4, 6, 8, etc. are on the engine side.
The second sensor on the engine’s exhaust pipe, often located after the catalytic converter, is known as Bank 2 Sensor 2. On Bank 2 denotes that the cylinders 2, 4, 6, 8, etc. are on the engine side.
P0420 or bank 1 is it?
What the P0420 Code Indicates Catalyst System Efficiency Below Threshold (Bank 1)” is the meaning of the code P0420. Simply explained, this code means that the computer in your automobile has noticed poor performance from the Bank 1 catalytic converter.
What code is sensor 2 in bank 1?
The Engine Control Module (ECM) assigns the OBD code P0036, which stands for “HO2S Heater Control Circuit – Bank 1 Sensor 2,” when it notices a potential issue with the bank. one additional sensor or sensor 2-circuit heater control
What does bank 1 of P0420 mean?
The P0420 error code denotes poor catalyst system performance. This code indicates that your car’s oxygen levels are below the required threshold (Bank 1), which is typically the consequence of issues with the fuel or exhaust systems. It can occasionally be difficult to diagnose
What does it mean to be a lean bank 1 or lean bank 2?
Code P0171 denotes a lean fuel mixture in Bank 1 of the engine. P0174 indicates a lean fuel mixture in Bank 2 of the engine. On the same side of the engine as Engine Cylinder 1 is Engine Bank 1. The opposing side of the engine is Engine Bank 2.
What is bank 2 sensor 2’s O2 sensor?
O2 Sensor Circuit High Voltage is the meaning of Diagnostic Trouble Code (DTC) P0158 (Bank 2, Sensor 2). The O2 sensor 2 measures the amount of oxygen in the exhaust gases leaving the catalytic converter and is the downstream O2 sensor (cat)
What does Nissan P0420 mean?
A P0420 code simply indicates that your car’s catalyst system efficiency is below threshold (Bank 1). The P0420 error code denotes a poor performance of the catalyst system. Problems with the fuel or exhaust systems of your car are typically to blame for this. Sometimes it can be challenging to diagnose.
Are the two O2 sensors identical?
Regarding your 2013 Chevrolet Cruze, the upstream and downstream oxygen sensors are not the same. The upstream oxygen sensor, also known as an air fuel sensor, is positioned before the catalytic converter and used to compute the air fuel mixture. The downstream sensor, which reads the emissions after the catalytic converter, is a heated oxygen sensor. They are similar in function but sufficiently dissimilar to prevent swapping. A skilled expert from YourMechanic may visit your location to assess the system and replace any defective O2 sensors if you need assistance getting this checked or fixed.

How can you identify the bad O2 sensor?
- Check engine light that is illuminated. If you have a malfunctioning oxygen sensor, your dashboard’s bright orange Check Engine light will often glow.
- poor gas mileage
- A rough-sounding engine
- Failure of the Emissions Test.
- A more aged vehicle
Where are the oxygen sensors?
The exhaust system houses the oxygen sensor. It might be seen on the exhaust manifold or close to the engine. Numerous oxygen sensors are included in many cars, but they all measure the amount of oxygen in the exhaust.
The second oxygen sensor, if the vehicle has one, will be found behind the catalytic converter. By comparing data taken before and after the converter, this sensor keeps track of how well it is working.
