Oxygen Sensor There are (2) or (4) O2 sensors on some vehicles. When you start looking at the O2 sensors, they are normally numbered something like "Bank 1 Sensor 1" Bank 1 is before the catalytic converter; Bank 2 is after the catalytic converter. Normally it is the upstream sensors (sensor 1) that go first. They see the harshest conditions. You will need; Oxygen Sensor Socket Anti-Seized Penetrating Oil Sometimes it will take 15 minutes or take a few hours it depends on your luck...
That means that your o2 sensor is stuck lean (bank 1 sensor 1)
The bank 1 sensor 1 oxygen sensor on a 2002 Honda Accord is located on the header. It is right next to the sensor circuit.
3, sensor 1 bank 1, sensor 2 bank 1, sensor 2 bank 2
On a 2006 Dodge Dakota bank 1 sensor 1 is driver side above the catalytic converter.
which sensor is for bank 1 sensor 1 on a 2006 nissan xterra
Bank one sensor one on a 2006 Ram is before the catalytic converter on the driver side.
Bank 2 sensor 1 (Air fuel ratio sensor)
That is the sensor in the catalytic converter.
bank 2 is the drivers side of the engine sensor 1 is before the exhaust enters the catalytic converter
Bank 1 would be the bank of cylinders that contain the number 1 cylinder. If it is a 4 cylinder engine there is only one bank. So, bank 1 sensor 1 would be the first sensor you come to in the exhaust system leaving bank 1 of the engine.

It will be the lower of the O2s (furthest away from the engine on bank one). If its a v-6 bank 1 is usually where the # 1 cylinder is.
