screwed into the driver's side exaust pipe, in front of the catalytic converter. The one after the catalytic converter is bank 2 sensor 2. Here is is a more complete description: The O2 sensors are screwed into the exaust system at various points. Some people say that there are 4 oxygen sensors, but technically, that is not correct. Only the front 2 are considered oxygen sensors. They are screwed into the exaust pipe, one on each bank, after the exaust manifold, but before the catalytic converter. Sometimes they are screwed directly into the exaust manfold itself. They are labeled Bank 1 sensor 1 ad bank 2 sensor 1. The other 2 are actually called catalyst moniters. They are labeled bank 1 sensor 2 and bank 2 sensor 2. They are oxygen sensors, but they serve a different purpose. They moniter the activities of the catalytic converters, thus the name, catalyst moniters. They are screwed into the exaust one on each bank,after, or downstream, of the catalytic converters.

bank 1 means cylinder 1-3 side, sensor 2 means the sensor after the catalytic converter.
bank 2 is the drivers side of the engine sensor 2 is downstream of the catalytic converter ( after the exhaust has passed through the catalytic converter - called a catalyst monitor )
where is the oxygen sensor location on a 1998 explorer bank 2 sensor
bank 1 is the passenger side of the engine sensor 2 is after the exhaust has passed through the catalytic converter (downstream)
On a 1997 Ford Explorer XLT : Bank 1 is the passenger side of the engine ( 4.0 liter SOHC , V6 , and 5.0 liter V8 ) Sensor 1 would be close to the engine BEFORE the exhaust enters the catalytic converter

Is this bank 2 sensor 1 or sensor 2?
That would be the O2 sensor located after the catalytic converter.
On a 1997 Ford Explorer : Bank 2 is the drivers side of the engine ( 4.0 liter EFI V6 , 4.0 liter SOHC V6 , 5.0 liter V8 engines ) Sensor 1 is close to the engine BEFORE the exhaust enters the catalytic converter Sensor 2 is AFTER the exhaust has passed through the catalytic converter
The bank 1, sensor 3, O2 sensor would be the O2 sensor post cat.

Bank 1 refers to the location of the bank of cylinders that contain the #1 cylinder. Sensor 2 refers to the Oxygen sensor after the catalytic converter. Bank 1 is the left side of the engine, in this case against the firewall, and Sensor 2 is past the catalytic converter on that bank.
bank 2 is passenger side, sensor 2 is rear sensor (after catalytic converter)
Bank 1 sensor 2 is the sensor on the downstream side of the catalytic converter.
That is the sensor in the catalytic converter.
The bank without a number onc cylinder in it is bank number 2. Sensor 2 is behind the catalytic converter.
bank 2 sensor 2 is the passenger side, rear sensor, it is located behide the catalytic converter.
It is the sensor below the catalytic converter.
This would be the sensor after the catalytic converter.
bank 1 = passenger side bank 2 = driver side sensor 1 = pre-cat sensor 2 = post-cat
bank one is the rear head, sensor 2 would be the lower one
That would be the sensor after the catalytic converter.
