Why is the catalytic conversion warning light on? What is the reason the catalytic conversion fault lamp comes on ?….
Catalytic converters are one of the most important components in modern cars. These components are essential for improving air quality, particularly in densely populated areas. The converter’s elements use chemical reactions to separate harmful gases from exhaust and make them harmless.
The catalytic convert works with oxygen sensors in the exhaust system to monitor exhaust fumes. The oxygen sensors send information to the ECU/PCM/ECM with the voltage signals they produce if the system is malfunctioning or inefficient.
Why is the Catalytic Conversion Malfunction Lamp On?
This light alerts the driver if the catalytic convert is not functioning efficiently or is too hot. The catalytic converter’s interior is designed in the form of a honeycomb to increase its contact with the air. As the metal deteriorates, the holes in the catalytic converter become clogged and restrict airflow. This can lead to overheating issues. The oxygen sensors may also fail, causing the computer to misdirect.
Before replacing the catalytic convertor, oxygen sensors must be checked. Modern cars don’t have separate warning lights for the converter. The check engine light illuminates to notify the driver of any converter problems. If one of these lights are on, your vehicle could experience reduced throttle response or loss of power. Sometimes you might not notice any difference. Depending on the fault, the on-board computer stores a code in its memory. A scan tool can help your mechanic determine the cause of the fault.
