I work two jobs and never had time to go to the mechanic and get my car fixed. After I found Yourmechanic, it was a no brainer. After booking Chad for an engine overheating diagnostic, he came to my job and found out exactly what was wrong with my car. After telling him that I was going out of town the next day, he found a time that worked best for me so that he can ensure that me and my car made it to my destination without breaking down and fixed my car THAT NIGHT! Great service, and the man is magic with my car. Fixed the problem the first time and for about half the price that an autoshop had quoted me. I highly recommend Chad for any auto-repair!

All about Oxygen Sensor Replacement

With each new model year, manufacturers are adding more oxygen sensors to better manage engine operation. Some high performance engines have an oxygen sensor for each cylinder as well as one for the rear of each catalytic convertor. The sensors are located either underneath the hood or underneath the car. The oxygen sensors are connected (screwed) to the exhaust pipe, either in front or back of the catalytic converter. The front (upstream) sensors measure the amount of oxygen in the exhaust system. The purpose of the front oxygen sensor(s) is to measure how rich or lean the gases are as the gases exit the combustion chamber. Depending upon whether the exhaust gas is lean (high in oxygen content) or rich (low in oxygen content), the amount of fuel entering the engine is adjusted by the engine management computer to try and maintain an ideal mixture that produces the lowest emissions output from the catalytic convertor. Rear (downstream) sensors are located behind the catalytic converter. The purpose of the rear oxygen sensor(s) is to monitor the oxygen content of the exhaust gases leaving the catalytic convertor. If one or more of the oxygen sensors are faulty, your car may not pass the emissions test. If you drive your car with a faulty oxygen sensor, you may get poor gas mileage and it can damage the catalytic converter.
