Another common reason for catalytic converter failure is the use of leaded gasoline. Leaded gasoline used to be common, but it's now illegal in many countries because it damages the environment. Even small amounts of lead can damage a catalytic converter and cause it to fail.
Finally, another common reason for catalytic converter failure is overheating. Catalytic converters can reach temperatures of over 1,000 degrees Fahrenheit (538 degrees Celsius), so it's not surprising that they can be damaged by excessive heat. Overheating can be caused by things like engine problems or excessive idling.
Catalytic converters play an important role in emission control, but they can sometimes fail due to engine misfire, leaded gasoline, or overheating. Suppose you think your catalytic converter might be failing. In that case, it's essential to take your car to a qualified emissions control mechanic as soon as possible so they can diagnose and fix the problem before it causes any further damage.
