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

[JanelleFitz]

The solutions for the three-way catalytic converter warning light coming on 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 damaged oxygen sensor. In this case, take the car to a repair shop or 4S store for professional repair or replacement of the oxygen sensor. Below are some tips on how to prevent three-way catalytic converter failures: 1. 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. Therefore, avoid idling for more than 10 minutes. 2. Avoid using leaded gasoline and oil additives, as they act like slow poison for the catalytic converter and will eventually cause failure over time. 3. Develop good driving habits. Since the catalytic converter is located under the car, be cautious when driving on gravel or rough roads. Try to take detours if necessary. If the three-way catalytic converter hits the ground, it will inevitably be damaged.
