An illuminated check engine light or malfunction indicator lamp (CEL or MIL) with a catalytic converter diagnostic trouble code (DTC) is the most common catalytic converter problem indicator. Failing the annual or semi-annual emissions test might also be linked to a failed catalytic converter.A rattling noise when starting the engine might indicate a broken catalyst. If the catalytic converter's housing is discolored or warped, there may be internal leakage or overheating.Ammonia (NH 3) odor may also indicate poor catalyst function. A sulfur or "rotten egg" smell indicates the formation of hydrogen sulfide (H 2S), a likely sign of catalytic converter contamination. A clogged catalytic converter essentially "suffocates" the engine, preventing it from "exhaling" the exhaust. These issues could indicate a clogged catalytic converter, restricting the flow of exhaust out of the engine.
