The quick responsiveness of your customer service portal and of your customer service personnel over the phone is extraordinary. I was a little reluctant to try YourMechanic.com at first, but the YourMechanic team that came to my door brought his A-game expertise and his A-game professionalism with him. Right away, he pointed out what he would do to undertake daignosing the root cause of the engine problem, and plan out how to implement an effective fix. He took the time to clearly explain where the problem was, and did not mind explaining it more than once for clarity as I'm not tech-savvy. And once he concluded, he made sure to show me what he indicated in his report, for my peace of mind and for total transparency. Very mindful of how valuable and flat-out superb the service you provide is, that is the impression me and my family have of YourMechanic.

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.
