The upstream oxygen sensor(s) monitor the level of oxygen in the exhaust gases as they leave the engine. A signal is sent to the computer (PCM) and the air/fuel mixture is constantly being adjusted to maintain a 14 to 1 ratio air/fuel mixture. The downstream oxygen sensor(s) monitor the efficiency of the catalytic converter(s). Nothing else. That's all they do. When replacing an oxygen sensor you must specify whether you want the upstream or downstream oxygen sensor. HTH. -Jim
