The Illuminated Check Engine Light Could Be Caused by a Faulty Catalytic Converter

It might seem strange, but if your catalytic converter goes bad, this could be the reason why the check engine light has turned on. Empire Auto Care can inspect the converter and replace it if necessary. Aside from an illuminated check engine warning light, we are going to list the other signs of a faulty catalytic converter below. Bring your vehicle to our shop right away if you notice any of the following problems.

Sluggish Engine Performance

The most common reason why a catalytic converter malfunctions is that it is clogged. As it treats your vehicle’s exhaust, carbon and sulfur are deposited onto the honeycomb interior of the converter. Unfortunately, once the converter gets clogged, exhaust will back up into the combustion chamber. When this happens, your engine performance lags because the combustion is affected.

Noticeably Poor Gas Mileage

This sluggish engine performance will directly affect your vehicle’s gas mileage. Unfortunately, it will reduce it because the engine will burn more fuel than it normally does in an effort to produce power. Replacing the catalytic converter will restore your engine’s performance. Once your engine is running efficiently again, you will start to get normal gas mileage out of the vehicle.

Dark Engine Exhaust Smoke

Another sign that the catalytic converter is going bad is dark exhaust smoke flowing out of the tailpipe. This smoke suggests that the converter was unable to treat the engine’s exhaust before it is released out of the tailpipe. This can affect the emissions levels in your exhaust and cause your vehicle to fail an emissions test if you live in a state that conducts emissions testing.

Exhaust That Smells Rancid

Aside from being black, your exhaust may also smell rancid. Specifically, it may smell like rotten eggs because the sulfur deposits will melt when the exhaust flows over them. In fact, rancid exhaust odors are one of the most common signs of a malfunctioning catalytic converter. It’s important to have the converter checked right away so it can be replaced if necessary.

Heat Underneath the Vehicle

Finally, a malfunctioning catalytic converter can release too much heat underneath your vehicle. As this heat rises, it will begin to affect your engine’s temperature. Unfortunately, it will cause your engine to overheat constantly. Replacing the catalytic converter will solve the problem.
