exaust leaks , faster if its before the 02 sensor
If it is bad the check engine light will come on and set a code for that particular sensor.
You have a bad 02 sensor after the catalytic converter.
The check engine light will illuminate if you have a bad O2 sensor. The code set will lead you to the faulty sensor.
engine will stall out and run very bad.
When a O2 sensor goes bad the check engine light will illuminate. The code set in the ecm will lead you to which O2 sensor is bad.
if your ac is running and if you have a bad 02 sencor most likely it will not kill your car it depends on your sensor
Not likely. A bad O2 sensor would illuminate the check engine light and the engine performance would suffer.
gas gouge no work
Most likely NOT.
The check engine light would illuminate and the code set would help lead you to which sensor is at fault.
If you are not getting an error light, you can check the color and oder of the exhaust. Dark exhaust means the car is running "rich" and that can be due to the 02 sensor telling the computer there is not enough fuel.Bad O2 sensors will cause loss of power and fuel economy.
