How long does a catalytic converter take to reach operating temperature?
Early types of catalytic converters typically took about 10–15 minutes to warm up, so they were completely ineffective for the first few kilometers/miles of a journey (or any part of a very short journey). Modern warm up in only 2–3 minutes; even so, significant emissions can still occur during this time.
Should a catalytic converter be hotter outlet?
When a catalytic converter is working properly, it will be 100º F hotter at the outlet than it is at the inlet. First, make sure the engine is up to operating temperature. You should see an outlet temp that’s 100º F hotter than the inlet temp. If you don’t, the catalytic converter is bad and should be replaced.
What is the operating temperature of a catalytic converter?
What Is the Operating Temperature of a Catalytic Converter? The normal operating temperature of a catalytic converter is between 550 and 1,600 degrees Fahrenheit with the optimum temperature being about 806 degrees. High operating temperature can be a sign of extra pollutants in the exhaust system.
How can I tell if my catalytic converter is hot?
Temperature measurements indicate if the converter is operating excessively hard. You can use a temperature probe to check if the converter is working abnormally hot. If the converter outlet hotness is 200 0 F higher than the inlet temperature, it means it has lots of unburned CO in exhaust system.
How can I test the efficiency of my catalytic converter?
Still, you can test your catalytic converter efficiency using a suitable kitchen thermometer, or better yet, an infrared thermometer like this one (recommended). Start the engine and let it idle for about 20 minutes to bring it up to operating temperature. Or take your car to the highway and then come back home.
How does a catalytic converter reduce harmful emissions?
A catalytic converter reduces the following harmful exhaust emissions: oxides of nitrogen (NOx) (three-way converter) It’s possible that during normal operation, the converter can succumb to age and lose the ability to catalyze emissions. But this is rare. Most catalytic converters outlast the engine.

How to test catalytic converter with infrared thermometer?
The catalytic converter is usually located close to the engine so you only need to raise the front. Place car stoppers against the rear wheels for added safety. Take an infrared thermometer and measure the temperature at the front of the catalytic converter. You only need to measure the surface temperature so an infrared thermometer is perfect.
