Which risk increases when catalytic converter internal temperature exceed maximum threshold limit?

💡 Explanation

When catalytic converter temperature exceeds limits, sulfur poisoning occurs because high heat promotes stronger sulfur-catalyst binding, blocking active sites and decreasing efficiency. Therefore sulfur poisoning risk increases, rather than improved oxidation/reduction, which require optimal temperatures below the threshold.
