What happens when the O2 sensor goes bad on a Mazda CX 5?
When an O2 (oxygen) sensor go bad, it’ll cause your Mazda CX-5 ‘s engine to run less efficiently. Your CX-5 can exhibit symptoms when the Oxygen sensor has gone bad. Or, it may exhibit none at all. Often enough, the only sign of the problem at all is the service engine soon light being on.
How does the O2 sensor in a car work?
The O2 sensor in your vehicle monitors the exhaust gases coming out of the engine. It determines the amount of oxygen in the gases, which indicates how well the fuel is being burned. The O2 sensor then sends information to the electronic control unit, or ECU, the vehicle’s computer.
Where are the oxygen sensors on an Audi A3?
There are many oxygen sensor related codes. These codes correspond with what side of the engine they are on (known as the “bank” for cylinder bank) and how far down stream they are. For instance, an oxygen sensor at bank 1 – sensor 1 would be: Bank 1- Side of the engine with the first cylinder in the firing order.
Can a bad oxygen sensor cause the Check Engine light to come on?

Where is the oxygen sensor in the engine?
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.
