Joshua could not have been a better representation for this company and for himself. He was on time and called in advance to let me know he was on his way. Not only was he professional but he also fully explained to me the issue I had with my car when both Mercedes dealerships (Pleasanton and Walnut Creek) just gave me a quote to fix with out any detail. I was so happy not only with the cost of service but the quality of the service which is a high bonus. I have already recommended Joshua to two other colleagues who have mercedes but also Yourmechanic.com to 2 family members as well....who have already recommended the company to others....The power of good service. Thx Joshua.

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.
