Why Do Converters Fail?

Converters don’t fail on their own. Converter failure is usually an indication of a larger problem. For instance, a faulty fuel injector can inject too much fuel into an engine. This raw fuel will make its way to the converter, causing the converter to overheat. Left unchecked, this overheating will melt the brick in the converter, rendering the converter useless.

There are a number of additional reasons for converter failure, and a variety of common engine management components that should be checked when replacing a converter.

Types of Converter Failure

Overheated, Melted or Broken Throttle Body Injector Fuel Injectors Throttle Position Sensor (TPS) Mixture Control Solenoid Idle Speed Control Motor	Coated / Oil-Fouled Substrate Engine Coolant Temperature Sensor (ECT) EGR Valve Position Sensor Head Gasket	High NOx, Exhaust Emissions Front Oxygen Sensors Air Charge Temperature Sensor (ACT) Idle Air Control Valve (IAC) Canister Purge Valve Manifold Absolute Pressure Sensor (MAP)	Road Damage Speed bumps Road Debris Potholes / Pavement Deterioration
