How O2 sensors work
I was just wondering if anyone could explain exactly how O2 sensors work. I am running my car without the exhaust from the 3rd cat back and am getting a "check engine". The O2 sensors are plugged in but could this be setting off a code. Wouldnt the sensors only care about what is infront of them and not behind?

http://www.mr2.com/TEXT/O2_Sensor.html hope that answers your question. the o2 sensor is the heart(well actually nose) of the emission control (and on modern cars) fuel injection system. nipper |
