Oxygen sensors, or O2 sensors, are small instruments in your car that measure the amount of oxygen in the exhaust. As you may know, your engine needs When there is a lack of oxygen, the engine runs rich, making it challenging to accelerate.

When your engine suffers from drastic pressure changes, it can affect the air pressure.
