Did a great job in installing the new brake pads (rear). Even advised that the rotors were fine and didn't require replacement. Highly recommended for quality, reliable, transparent, and fair service.

I am completely satisfied with the service Patrick provided. He was very professional and listened to all of my concerns (unlike the dealer service department). Patrick and YourMechanic communicated every step of the way. I would recommend Patrick to anyone needing service on their vehicle.

Chris checked everything out and showed up early which was great! He texted me and I called them once he got done looking over the car. He explained everything to me and let me know that was one of the best conditions he seen a car of that year and model. After talking with Chrys I definitely have much more confidence in purchasing the car. I will definitely let my friends and family know about their service.

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.
