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.
An Oxygen sensor that is between the catalytic converter and the engine is known as an “upstream” sensor. Oxygen sensors after the catalytic converter are “downstream sensors”. As a rule, the upstream sensor is more important for engine timing and air/fuel ratios.

What causes an error code on the O2 sensor?
Even if the error code is caused by the O2 sensor, be aware that most of the time it’s not the sensor itself that’s malfunctioning, but it is catching problems caused by other parts of the engine. Before you replace the O2 sensor, you should inspect your vehicle for any air leaks or loose gaskets as those could also cause an error.
