Patrick showed up early for our appointments, went over the issues of my car and laid out the options of what I could do afterwards. He is very down to earth and is honest about the problem at hand. My car was having a problem overheating so after inspecting the car and troubleshooting he said that the car might have to require work on it up to $800+ which they could do but he suggested that there were other cheaper options for me to try. I would totally recommend him.

Kenneth was exceptional. I hadn’t used YourMechanic before, but it couldn’t have gone more smoothly. I will definitely use the service again based on this experience and will, of course, request the same mechanic. Kenneth sized up the problem with my car right away and went above and beyond to fix it. On a Saturday. I really appreciate that. He was professional, personable, and explained everything as he went along. And my car runs perfectly! I also really liked the email alerts about the arrival time, and the prices are better than other estimates I got online. Thank you!

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.
