What particularly impresses me about Shaun is the level of service and unwavering professionalism he displays. He understands that my knowledge about auto mechanics is next to nothing. He patiently works with me to identify my concerns, takes time to explain and offer solutions. The work that Shane does should be held up as an example for others to try to emulate. I believe that Shane deserves to be commended for his service which is always well beyond my expectations.

Working with Brian Z. was a 10 out of 10 experience. It was my first use of YourMechanic.com, and it will not be the last so long as he's on the case. Brian came by on time and quickly changed out both my rear differential and my power steering fluids. Along the way, he accurately noted the other areas where the car needed future maintenance. Brian's love for this work shines through in his professionalism and abundant knowledge, in particular of Nissan products. I will be asking for him from now on for my car repair needs!

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.
