Warning Lights Associated with Catalytic Converter Problems
The most common warning light associated with catalytic converter problems is the Check Engine Light (CEL). This light is a general indicator that something within your vehicle’s emission system, including the catalytic converter, isn’t functioning correctly. The CEL may come on due to a variety of reasons, such as a failing catalytic converter, oxygen sensor issues, or exhaust leaks. If the light appears, it’s important to get your vehicle diagnosed promptly, as it could indicate that the catalytic converter is clogged or inefficient, potentially impacting your car’s overall performance.
The Exhaust Temperature Warning Light
Some vehicles, particularly those equipped with more advanced diagnostic systems, have a specific Exhaust Temperature Warning Light. This light comes on when the exhaust system reaches an excessively high temperature, which can be a sign of a clogged or failing catalytic converter. When the converter is working inefficiently, it may overheat because it’s unable to properly filter out harmful gases. An overheating exhaust system can cause engine performance problems and increase the risk of a fire. If this light illuminates, it’s essential to stop the car and let it cool down before seeking professional repairs.
The Service Vehicle Soon Light
In some cars, particularly older models or vehicles with specialized diagnostic systems, a Service Vehicle Soon light may illuminate. While not as common as the CEL, this warning light specifically indicates that the vehicle’s emission system needs attention. It could mean that the catalytic converter is no longer functioning optimally. If you see this warning, it’s crucial to have the vehicle checked immediately as delayed repairs could lead to further engine or exhaust system damage.

The Reduced Power Light
The Reduced Power Light (also known as the “limp mode” indicator) could also be related to a catalytic converter issue. When the converter becomes clogged or inefficient, it can restrict the flow of exhaust gases, causing the engine to overheat or lose power. In response, the vehicle’s onboard computer may activate limp mode, limiting engine performance to protect it from further damage. If your vehicle enters limp mode and you notice sluggish acceleration or reduced power, a failing catalytic converter could be the culprit.
The Low Fuel Economy Light
Although rare, some vehicles may trigger a Low Fuel Economy Light or display a drop in fuel efficiency when the catalytic converter is malfunctioning. When a catalytic converter is damaged or blocked, it may cause the engine to work harder to expel gases, which can lead to an increase in fuel consumption. If you notice a significant drop in fuel economy, coupled with other performance issues, it’s worth having the catalytic converter checked.
Recognizing these warning lights early and seeking professional help can prevent more severe damage to your vehicle’s catalytic converter and exhaust system. Prompt attention to warning signals helps protect your engine’s health and reduces the risk of costly repairs.
