We often get asked: “Where is Bank 1 Sensor 1?” To answer that question, we decided to show you a few pictures of Bank 1 Sensor 1 to help you identify it on your car. On a four-cylinder engine, it is straightforward to locate the O2 sensor 1 bank 1.
On a six, eight, ten, or twelve-cylinder engine, it gets tricky to determine which one is Bank 1 sensor 1 because those cars typically have two upstream sensors. Many car manufacturers assign the passenger side of the engine as Bank 1 and the driver side as Bank 2, which is often the case in most European vehicles.

What does Bank 1 Sensor 1 Mean?
These oxygen or O2 sensors are located between the bank 1 cylinder head and the corresponding catalytic converter. The task of this sensor is to measure the composition of raw exhaust fumes. This important data helps ECU adjusts the air-fuel mixture for optimum efficiency.
Is Bank 1 Sensor 1 Upstream?
On all cars, bank 1 sensor 1 is an upstream oxygen sensor. You will find it on the exhaust side, closest to the bank 1 cylinder head. It is easy to spot in-line engines, while it is important to find out which is the bank 1 side on V-shaped engines.
How to change O2 sensor Bank 1 Sensor 1?
After locating it in your car, replacing the sensor is just a matter of undoing several bolts or unscrewing the sensor itself. However, access can be tricky in most cars because of limited space, so you will need a special O2 sensor socket. As a preparation step, disconnect the wire plug and spray some penetrating oil onto sensor threads. When installing a new one, add some anti-seize to the threads and tighten it to the specified torque.

Being a classic truck with a rear-wheel-drive configuration, F-150 has a longitudinally-mounted engine. Also, all newer F-150 models have V-shaped engines. Despite their differences in capacity and number of cylinders, they all have a bank 1 sensor 1 on the passenger side.
Where is Bank 1 sensor 1 on a Toyota?
As with any other vehicle, this depends on the engine type and drivetrain configuration. On most in-line engines, the Bank 1 sensor 1 will be located at the engine’s front side, near the cylinder head. On most front-wheel-drive models with V6 engines, this sensor will be on the backside against the firewall. Most rear-wheel-drive cars and pickups will have this sensor on the passenger side.
Can you clean a Bank 1 sensor 1 O2 sensor?
The O2 sensor’s core is a special sensing element inside a shell with a series of holes around it. Although it is possible to remove build-ups using a brush from the protective shell, this will not clean the sensing element itself. Special solutions can be used for this purpose, but their performance is not that reliable.
