How to Solve the Malfunction Indicator Light Caused by the Three-Way Catalytic Converter?

[VonParker]

The solutions for the malfunction indicator light caused by the three-way catalytic converter are as follows: 1. First, decode the car's computer. 2. If the light remains on after decoding, it indicates that the issue is not with the computer but likely a faulty oxygen sensor. In this case, visit a repair shop or 4S store to have professionals repair or replace the oxygen sensor. Below is an introduction on how to prevent three-way catalytic converter failures: 1. First, reduce idling time while driving, as prolonged idling increases the engine's internal temperature. The catalytic converter has a temperature limit, especially in summer when temperatures are already higher than usual, so be cautious and try not to idle for more than 10 minutes. 2. Second, avoid using leaded gasoline and oil additives, as they act like slow poison for the catalytic converter and will inevitably cause malfunctions over time. 3. Develop good driving habits. Since the catalytic converter is located under the car, drive carefully when encountering gravel roads or poor road conditions, and try to take detours if necessary. If the catalytic converter gets scraped by the road, it will inevitably be damaged.
