Answers :

Think of the 02 sensor as the muscle behind the brain. What it constantly is saying to the PCM thousands of times a minute is to much fuel, to little fuel, over and over and over again. As far as cost call any parts house. You have four so if you replace one get the right code so you know. left front code will be b1s1( bank one sensor one.) Or something like that. Its located on the exhaust under about where you sit.
Automotive oxygen sensors, colloquially known as O2 sensors, make modern electronic fuel injection and emission control possible. They help determine, in real time, if the air fuel ratio of a combustion engine is rich or lean. Since oxygen sensors are located in the exhaust stream, they do not directly measure the air or the fuel entering the engine.
