Godwin from YourMechanic was amazing. Very knowledgeable and polite, answered every question and explained very well for my not so car savvy self. Work was amazing an professional. Let me know what he was doing or needed to next. Sent me an estimate of what other fixes need to happen. Will never use anyone else to service my car.

Although they tell you to give the mechanics 1 hour leeway to show up, Armando was at my house early. He serviced my car perfectly and took the time to explain to me exactly what he was doing and why. He also completed a full inspection on the rest of my car to let me know what I should focus on fixing next. Definitely looking to schedule with him again. Great experience!

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.
