Do you have problems with oxygen sensor?

The main task of the oxygen sensor is to check an oxygen level and report to the powertrain control module (PCM). The amount of oxygen in exhaust gasses indicates whether the air-fuel mixture supplied to the combustion chambers is correct. Too much oxygen indicates that the mixture is lean; too little indicates it’s running rich. When the computer sees either of these scenarios, it adjusts the amount of fuel supplied accordingly. A bad oxygen sensor tells the PCM to add or reduce fuel when it doesn’t have to, giving you a few headaches.
