What to Do When the Three-Way Catalytic Converter Aging Malfunction Light Comes On?

[DiBrielle]

Decode the vehicle's computer. If the light remains on after decoding, it indicates that the issue is not with the computer but likely with the vehicle's oxygen sensor. Below is relevant information: 1. Three-Way Catalytic Converter: The three-way catalytic converter is an external purification device in the vehicle's exhaust system. Since the catalyst primarily consists of three precious metals and can catalyze the three most harmful pollutants through oxidation and reduction reactions, it is appropriately called the three-way catalytic converter. 2. Preventive Measures: Reduce idle time while driving, as prolonged idling can raise the engine's internal temperature. The catalytic converter has a temperature limit, especially in summer when temperatures are already higher than usual. Therefore, it's essential to avoid idling for more than 10 minutes. Additionally, avoid using leaded gasoline and oil additives.
