• There will be at least one sensor at the front of the vehicle, mounted into the exhaust pipe or manifold somewhere before the catalytic convertor.
  This is known as the front, pre-cat or upstream sensor.
  V-type engines (V6, V8 etc) will often have one pre-cat sensor for each bank of cylinders.
  
  
• There will then be another sensor positioned after the catalyst, known as the rear, post-cat or downstream sensor.
