In engines, the terms Bank 1 and Bank 2 refer to the two sides of the engine's cylinders. Bank 1 is the side with cylinder 1, while Bank 2 is the opposite side, which typically contains cylinder 2. The specific configuration of cylinders in each bank depends on the type of engine, such as V-engines, inline engines, or transverse engines. To identify which side is Bank 1 and which is Bank 2, various methods can be employed, including checking the firing order of spark plugs, unplugging O2 sensors, or using an OBD2 scan tool. Understanding the layout of Bank 1 and Bank 2 is crucial for proper maintenance and repair, especially when dealing with O2 sensors or catalytic converters.

What You'll Learn
Bank 1 is the side with cylinder 1
The engine's cylinders are often divided into two parts, with one bank on each side of the engine for V-shaped engines. However, the location of cylinder 1 varies across different engines, so it is not always accurate to assume that bank 1 is on the driver's side.
Bank 1 is the side of the engine with cylinder 1. It includes cylinders 1, 3, 5, 7, 9, and 11. Cylinder 1 has the frontmost spark plug, intake rubber, and exhaust runner. Bank 1 Sensor 1 is the first sensor closest to the engine (upstream), and Bank 1 Sensor 2 is the second sensor on the engine's exhaust pipe (downstream), usually behind the catalytic converter.
To determine which side of the engine is bank 1, you can use an OBD2 scan tool. First, connect your OBD2 scanner and erase the trouble codes. Then, unplug one O2 sensor and check the DTC code. This method will help you identify which side is bank 1 and ensure that you replace the correct sensor.
Additionally, you can unplug an oxygen sensor and scan it for faults. If you get an O2 bank X circuit high, you can determine that it is bank 1. For Ford engines, bank 1 is typically on the right side of the engine with the forward-most cylinder (cylinder 1). In a longitudinal engine, this would be the passenger side, while in a transverse engine, it would be the firewall side.

Bank 2 is the side with cylinder 2
The engine's cylinders are often divided into two parts, with one bank on each side of the engine. However, it is not as simple as saying that bank 1 is on the driver's side and bank 2 is on the passenger side, as different engines can have cylinder 1 on different sides. For example, in Ford engines, bank 1 is always on the right side of the engine with the forward-most cylinder (cylinder 1). In a longitudinal engine, this would be the passenger side, whereas in a transverse engine, it would be the firewall side.
Bank 1 includes cylinders 1, 3, 5, and 7, whereas bank 2 includes cylinders 2, 4, 6, and 8. Therefore, bank 2 is the side with cylinder 2. To determine which side is bank 2, you can use an OBD2 scan tool. First, connect the OBD2 scanner and erase the trouble codes. Then, unplug one O2 sensor and check the DTC code. This method will allow you to determine whether it is bank 1 or bank 2 and will help you replace the correct sensor.
Bank 2 can be on both inline engines and transverse engines. It is important to note that the terms "bank 1" and "bank 2" refer to the sides of the engine with cylinder 1 and cylinder 2, respectively, and not the front or back of the engine. Additionally, these terms are not related to the exhaust or intake side of the engine.

How to locate which O2 sensor is bank 1 and bank 2
The engine's cylinders are often divided into two parts, with each side of a V-engine corresponding to a different bank. Therefore, to identify which O2 sensor is Bank 1 and which is Bank 2, you must first determine which side of the engine is Bank 1.
Bank 1 will always be on the side with cylinder 1. If you have an inline 4-cylinder engine, there will only be one bank. However, if you have a V6 or V8 engine, there will be two banks, with Bank 1 usually located on the driver's side.
To determine which side is Bank 1, you can use an OBD2 scan tool. First, connect your OBD2 scanner and erase the trouble codes. Then, unplug one O2 sensor and check the DTC code. This method will allow you to identify which side is Bank 1 and which is Bank 2, ensuring that you replace the correct sensor.
Additionally, you can identify Bank 1 by examining the block. The side with the most forward (belt side) cylinder is Bank 1. Alternatively, you can unplug an O2 sensor, and if you see B1S1/B1S2 codes, it indicates that it is Bank 1.
It is important to note that the location of Bank 1 and Bank 2 can vary depending on the vehicle's make and model. While Bank 1 typically corresponds to cylinders 1, 3, 5, 7, 9, and 11, and Bank 2 to cylinders 2, 4, 6, 8, 10, and 12, the firing order of your spark plugs and wires may provide a more accurate indication of their positions.

Upstream and downstream O2 sensors
The upstream and downstream O2 sensors in a vehicle correspond to its engine banks. The engine's cylinders are divided into two parts, with each side of the "V" in a V-engine being referred to as a bank. The bank that includes cylinder 1 is bank 1, and the other bank is bank 2.
The upstream O2 sensor (Sensor 1) is located before the catalytic converter, closer to the engine. It monitors the air-fuel ratio entering the converter to optimise combustion. The downstream O2 sensor (Sensor 2) is positioned after the catalytic converter, closer to the exit of the exhaust pipe. Its main role is to monitor the efficiency of the catalytic converter and ensure emissions meet environmental standards.
In most cases, a vehicle's exhaust system will have two independent oxygen sensors for each engine bank. The upstream sensor is positioned before the inlet of the exhaust catalyst, while the downstream sensor is positioned to the rear of this catalyst.
It is important to correctly identify the bank and sensor number when replacing an O2 sensor. Bank 1 Sensor 1 is upstream of (before) the catalytic converter, while Bank 1 Sensor 2 is downstream (after) it. For a V6 engine, there will be four sensors: Bank 1 Sensor 1, Bank 2 Sensor 1, Bank 1 Sensor 2, and Bank 2 Sensor 2. An inline engine will only have two sensors: Bank 1 Sensor 1 and Bank 1 Sensor 2.
There are methods to determine the bank and sensor number. One way is to use an OBD2 scan tool to check the DTC code. Another method is to determine the firing order of the engine's cylinders. Additionally, for Toyota vehicles, Bank 1 is often the passenger side (with Cylinder 1), and Bank 2 is typically the driver's side.

Bank 1 and bank 2 in V8, V6, and flat engines
In a V-shaped engine, the term "bank" refers to each half of the cylinders. In a V6 engine, Bank 1 contains cylinders 1-3, while Bank 2 contains cylinders 4-6. The same logic can be applied to V8 engines, where Bank 1 contains cylinders 1-4 and Bank 2 contains cylinders 5-8.
Flat engines, on the other hand, are typically used in motorcycles and aircraft. They offer advantages such as a low centre of mass, low vibration, suitability for shaft drive, and equal cooling of the cylinders. In a flat-twin engine, for example, there are two cylinders that work in opposition to each other, resulting in a boxer configuration. This type of engine is commonly found in motorcycles, such as the BMW R32. Flat-four engines are commonly used in cars, such as the earlier Volkswagen Types 1 to 4 and Subaru models, and they are also used in motorcycles and aircraft. Flat-six engines are used in some sports cars, such as the Porsche 911, due to their excellent primary engine balance and lower centre of gravity, which improves handling.
In summary, the concept of "Bank 1" and "Bank 2" specifically applies to V-shaped engines, such as V6 and V8 engines, where the cylinders are divided into two banks. Flat engines, on the other hand, are typically classified by the number of cylinders and the configuration of the pistons, such as the boxer configuration commonly found in flat-twin and flat-four engines.
