Symptoms of a Bad or Failing Oxygen Sensor 1 Check Engine Light comes on The first line of defense is the Check Engine Light. 2 Bad gas mileage and rotten egg smell If the oxygen sensor is going bad, the fuel-delivery and fuel-combustion systems will be thrown off. 3 Rough engine idle and misfires

Where is the oxygen sensor in the engine?

The oxygen sensor is located in the exhaust pipe and assists your engine in running efficiently while creating as little emissions as possible. Since a malfunctioning sensor sends false readings to the engine management computer, the engine uses up more fuel than necessary. This results in a drop in gas mileage and noticeably reduced performance.
