Why are catalytic converters so restrictive on cars?
The catalytic converters in the past were very restrictive because the exhaust coming from the combustion process was extremely toxic. Modern engines create less of an impact, which means the device creates almost the same effect as a straight pipe for the average vehicle on the road today that is less than 10 years old.
Can a catalytic converter be repaired without replacing the ECM?
Exhaust leaks are common and can skew oxygen sensor readings without setting other DTCs. A careful search might reveal exhaust leaks that, when repaired, “restore” catalytic converter function, at least from the point of view of the ECM.
What are the signs of a catalytic converter problem?
Signs of a Catalytic Converter Problem Engine accelerates poorly or is hard to start. A sulfur or “rotten egg” smell indicates the formation of hydrogen sulfide (H 2S), a likely sign of catalytic converter contamination. If the catalytic converter’s housing is discolored or warped, there may be internal leakage or overheating.
Can a broken catalytic converter cause an engine to overheat?
A broken catalytic converter is not uncommon at all. Any external impact such as debris on the road or overheating of the engine’s internal components can affect it. Let’s see some catalytic converter symptoms. 1. Engine Misfiring The catalytic converter can overheat and show signs of failing when the engine misfires.

Can a lazy oxygen sensor cause a catalytic converter problem?
You may need to fix other engine problems in order to solve your catalytic converter problem. A lazy oxygen sensor might falsely indicate a catalytic converter problem, yet not set a DTC for itself. A technician can determine if the sensor is responding as it should.
