In the VQ40, bank 1 is the passenger side and bank 2 is the driver. You got both upstream and downstream right. If a skid plate is not bolted in the way, you should have no trouble getting to the downstream bank 2 sensor. I can see mine even with the Hefty skid attached, but to have quick access, I’d need to remove the skid or get creative with some swivel extensions.

Can you tell me where this sensor is located? My 1999 Nissan Frontier v6 4×4 has the code P151 HO2S-21 (bank 2 sensor 1) circuit low input (lean shift).
With the belts and pulleys closest to you, observe the engine. The Left side of the engine is known as Bank 1. The right side of the engine is known as Bank 2. Within the exhaust system are O2 sensors. Within each exhaust are two. The catalytic converter is followed by Sensor Two, which is located after the catalytic converter.
On the right side of the engine is where you’ll find the sensor you’re looking for. As the exhaust rotates underneath the car, it will be mounted into the first part of exhaust.
To give you a general idea of what the sensor would look like, I’ve included an image.

I can see a figure in the repair manual with the O2 sensor on the driver’s side representing bank 1 and the passenger side representing bank 2.
On a number of other forums about cats and other repairs, a lot of users claim that Bank 2 is the Left side? Wouldn’t the driver’s side be on the left?
Can someone please tell me which is which for sure. Although I tend to believe the instructions, I know it is not flawless.
Which side of the engine is bank 2?
Simply put, banks 1 and 2 refer to the engine’s sides. Bank 1 is adjacent to cylinder 1 on that side. The side that has cylinder 2 is Bank 2. If a vehicle has a transverse engine, Bank 1 is often located toward the front of the vehicle.
Checking your car’s repair manual is the simplest way to find the correct cylinder bank. Additionally, you can look for any stamps bearing cylinder numbers on the cylinder head or block.
The crankshaft pulley is located at the front of the engine. The side of the engine that faces the front is not the front.
Because different engines can have cylinder 1 on different sides, you can’t generalize and claim that bank 1 is on the driver’s side or vice versa. Guessing which side bank 1 or bank 2 is on is just confusing and deceptive because people drive on different sides all around the world.
- The side with cylinder number 1 is known as Bank 1. (Cylinders 1 – 3 – 5 – 7 etc.)
- The side with cylinder number 2 is known as Bank 2. (Cylinders 2 – 4 – 6 – 8 etc.)
Is bank 2 on the left or right?
Not notably on the driver’s or passenger’s side is Bank 2. Bank 2 is similar to Bank 1 in that it does not have a fixed position or side. In some automobiles, they are on the driver’s side, whereas in others, they are on the passenger side. Everything is dependent on the manufacturer and type of engine.
Bank 2 could be on the driver’s or the passenger’s side. It’s important to remember that in every engine, bank 2 is the exact opposite of bank 1.
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.

Where is bank 2 sensor 2 located?
Sensor 2 Bank Bank 2 Location The O2 sensor for a car will be situated on the bank that corresponds to the second cylinder of the engine (bank 2, sensor 2), behind or downstream of the catalytic converter.
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.
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.
How does a car’s bank 1 work?
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.
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
The bank 2 oxygen sensor is where?
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.
How can I resolve bank 2 P0430?
- the catalytic converter being replaced.
- identifying and fixing engine misfire.
- Fuel injector replacement.
- repairing any engine technical issues.
- swapping out the oxygen sensor.
- Whether the exhaust has to be repaired or rebuilt
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 does P0430 bank 2 represent?
What the P0430 Code Indicates P0430 stands for “Catalyst System Efficiency Below Threshold (Bank 2),” a diagnostic problem code (DTC). The code alerts the driver to a catalytic converter issue located close to engine bank 2. (the side of the engine opposite the number one cylinder)
Sensor 2 is it downstream or upstream?
The upstream is always meant when the code reader refers to sensor 1 in a sentence. The downstream is always meant when the code reader refers to sensor 2. If you require more help with your oxygen sensors, get in touch with a specialist, such one from Your Mechanic.

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
Can an O2 sensor be cleaned?
An essential component of your car’s pollution control system is an oxygen sensor. Simply explained, an oxygen sensor measures the amount of emissions your automobile emits and transmits that data to the management computer in the engine. There are at least two sensors in your car, and when one of them malfunctions, you need to take action. Can an oxygen sensor be cleaned? Contrary to what you may have heard or read, such sensors should be changed when they malfunction.
Is it necessary to replace oxygen sensors in pairs?
O2 sensors should ideally be changed in pairs. For instance, you should replace the downstream right sensor if you replace the downstream left sensor.
On the majority of cars made after 1996, the ECU will set a code for the other sensors if one sensor is replaced, particularly the front engine monitoring sensor. This is due to the fact that new sensors switch activities considerably more quickly than do older, more seasoned sensors. On the majority of vehicles, the code is likely to be set between 30 and 60 days AFTER the first sensor replacement.
The meaning of code P0420?
What Does P0420 Mean? Do I Still Get to Drive? The P0420 error code denotes poor catalyst system performance. This code indicates that the oxygen levels are below the recommended threshold (Bank 1), which is typically caused by issues with your vehicle’s fuel or exhaust systems.
