Where is the the bank 2 sensor 1 OS location on a 1997 SOHC?

Answer 1

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.
