Timothy

Timothy was terrific, highly knowledgeable and very personable. I had scheduled an appointment to have my daughter's O2 sensors replaced, but after he got here and assessed the situation, he said that we didn't need them replaced. He cleaned out a few areas that might have been causing the problem which reset the check engine light. I didn't get charged for anything except a diagnostic and the gas treatment he put in the car. The repair shop we had originally checked with had said the sensors needed replacing and quoted us $400 to do so and I'm sure if we had gone there instead of with Timothy, they would have been replaced without actually fixing the problem. Timothy was up front about everything he was doing in the car and gave us a list of possible upcoming maintenance items. I loved the service and will definitely use it again.

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.
