For 2015 Hyundai IX35 Catalyst Catalytic Converter

Catalytic Converter and Mufflers When the exhaust gas is released by the engine, it first passes through the filter of the Three way catalytic converter. This process helps to reduce the concentration of harmful substances such as carbon monoxide, nitrogen oxides and hydrocarbons, thereby reducing the negative impact on the environment. Before and after the three-way catalytic converter, oxygen sensors are respectively provided, which are the front oxygen sensor and the rear oxygen sensor.   The front oxygen sensor acts like a monitoring station, monitoring the amount of oxygen in the exhaust gas and feeding the data back to the vehicle's electronic control unit (ECU) in real time. Based on this information, the ECU adjusts the air-fuel ratio of the engine to ensure an optimized combustion process.   Precise control of air-fuel ratio is crucial to engine performance. However, the role of the post-oxygen sensor is not so simple, it is responsible for checking the efficiency…
