Do you have problems with oxygen sensor?

Administrator posted this 13 July 2018

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.
