I was skeptical that MyMechanic was too good to be true! So much less expensive, and you do the work in my driveway?! We figured we'd give it a shot, and we are really glad we did. Casey is super-friendly and incredibly dedicated to his craft and his customers. We hit a snag when the repair was unexpectedly a little more complicated and took longer than estimated, and this had to mess up a good part of the rest of his day, but Casey didn't leave us hanging. He did what was needed to finish the job, and we were charged the original estimate even though it took longer than planned. We were really impressed with his commitment to us and the fidelity to the estimate. He also noticed some unusual, dangerous wear on our tires, which we thankfully were able to replace before going off on a long driving vacation the next day! Overall, the experience exceeded my expectations. Thanks, Casey and MyMechanic!

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.
