Honorio

Honorio diagnosed and fixed my power window + outlets despite one of the parts I ordered being defective. He took the extra time to explain to me what the problems were and how he was going about fixing them. In the end, the entire job took longer than expected but he honored his original labor quote. I couldn't be more satisfied with the job he did.

Kyle was professional and quick, and I appreciated the information he provided on the issue with my car. Although he did call to let me know his previous appointment ran late, he stated his ETA would be 20 minutes but ended up being an hour. My 10:00 appointment time ended up starting well after 11.

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.
