Catalytic converter efficiency test

The catalytic converter plays an important role in the vehicle's exhaust system and is responsible for reducing harmful emissions. When the efficiency of the catalytic converter drops, the Check Engine light often appears on the dashboard. A properly functioning catalytic converter is also required to pass vehicle inspections in New York and other states where smog testing may be performed. During diagnostics we use a professional scan tool to analyze oxygen sensor data before and after the catalytic converter. This helps determine whether the catalytic converter is failing or if the issue is related to a faulty sensor. Over time the ceramic element inside the converter can deteriorate, which may cause loss of engine power, poor acceleration, or unstable engine performance. For this reason proper electronic diagnostics of the catalytic system is important when these symptoms appear.
