On a Ford F-150, Bank 1 Sensor 1 refers to the upstream oxygen sensor located on the driver's side of the engine, before the catalytic converter. It is typically positioned in the exhaust manifold or just downstream of it. This sensor monitors the oxygen levels in the exhaust gases to help the engine control unit optimize fuel efficiency and emissions. The exact location may vary slightly depending on the specific engine and model year.
On a Ford F-150 ( V8 and V6 engines ) Bank 2 is the drivers side of the engine Sensor 1 is close to the engine before the exhaust enters the catalytic converter
They are located on the passenger side. Sensor1 is right past the exhaust manifold, and sensor 2 is after the cat.
A bank1 sensor1 refers to an oxygen sensor located in the first bank of cylinders in an internal combustion engine, specifically before the catalytic converter. In a V-type engine, "bank 1" typically denotes the side of the engine where cylinder number one is located. This sensor plays a crucial role in monitoring the exhaust gases to help optimize fuel efficiency and emissions by providing feedback to the engine control unit (ECU). Proper functioning of bank1 sensor1 is essential for the engine's performance and compliance with emissions regulations.

On a 2000 Ford Ranger , 3.0 and 4.0 liter V6 engines : Bank 1 is the passenger side of the engine Sensor 1 is close to the engine before the exhaust enters the catalytic converter ( it might even be in the outlet of the exhaust manifold )
On a 1998 Ford F-150 : Bank 2 is the drivers side of the engine ( for the 4.2 liter V6 and the 4.6 or 5.4 liter V8 engines ) Sensor 1 would be close to the engine before the exhaust enters the catalytic converter
On a Ford F-150, the Bank 1 Sensor 1 O2 sensor is typically located in the exhaust manifold or just after it on the driver's side of the engine. It is responsible for monitoring the oxygen levels in the exhaust gases before they enter the catalytic converter. Depending on the model year and engine type, access may vary, so it's best to consult your vehicle's service manual for specific details.
bank 1 is upstream bank2 is downstream sensor1 is on cylinder1 side upstream sensor 2 is the other side usually passinger side,bank 2 refers to sensor after converter
On the exhaust pipe next to the firewall. This is the one you change for a OBD code P01135.

On a 2009 Chevy Traverse, the oxygen sensor bank 2 sensor 1 is located on the exhaust system, specifically on the exhaust manifold or just downstream of it on the exhaust pipe. Bank 2 refers to the side of the engine that is opposite to bank 1, which is typically the side with the cylinder 1. To access it, you may need to lift the vehicle and work from underneath or remove some engine covers or components for better access.
