Which outcome occurs when a wastegate malfunctions in a turbocharged gasoline engine with high manifold pressure?

💡 Explanation

When the wastegate fails closed under high manifold pressure, boost pressure rises because it cannot vent excess exhaust gas, causing excessive cylinder pressure, and leading to detonation. Therefore, engine detonation results, rather than other outcomes such as bearing failure, pre-ignition, or catalyst damage requiring different failure mechanisms.
