First, it comes with dual laser instead of a single beam, allowing for greater precision when it comes to taking temperature measurements over certain distances. the exhaust gases. The outlet should be hotter than the inlet by 10% b. Jack Bennett has been working for Meter Test Lab since 2017. You only need to measure the surface temperature so an infrared thermometer is perfect. How Infrared Thermometer works To measure a surface temperature, the user aims the IR Thermometer at the target, presses a button, and reads the temperature display. This makes them difficult to remove because forcing the sensor loose can damage the boss threads. These vehicles use catalyst temperature sensors (rather than O2 or oxygen sensors) to monitor the efficiency of the catalytic converter. Also, the guys in the auto parts store can download the trouble codes for you and tell you what they mean. if you have an infrared thermometer you can check catalytic converter inlet & outlet temps and you may find that the cat is dead. Another method is to detach the catalytic converter from the header pipe that carries exhaust gasses into it. Portable IR thermometers have become indispensable tools for automotive troubleshooting and diagnostics. Firstly, it removes the excessive heat from the engine to avoid engine overheating. It requires frequent differential oil changes and is maintenance that you can easily do yourself. Take an infrared thermometer and measure the temperature at the front of the catalytic converter.

Highly recommended. He has certifications in automation and control technology. Using an infrared thermometer, check the temperature of the converter's front and rear weld rings, to ensure the converter has "lit off." Depending on their sizes, most converters begin to light off around 350°F, and are fully lit around 500°F. hardlymoving from Memphis, TN on May 09, 2020: The upstream to downstream temperature differential test is the dead give away. and replacement is required. Portable IR thermometers have become indispensable tools for automotive troubleshooting and diagnostics. claiming that you can find out if your catalytic converter is bad by checking the temperature (using an IR thermometer) of the cat (close to the O2 sensor) and the pipe before (close to the engine) and after the cat. Is that fahrenheit or celcius? Using a pyrometer or infrared thermometer, read and note the temperature of the pipe just ahead of the converter inlet at the weld ring. Catalytic converter test guide. In some cases, the car won't' start. following test will work for both primary and secondary but the difference in Utilizing a There really is no way to check it with an infrared thermometer the catalytic converter is usually always going to read between 700° and 900°. My registration renewal is a few months away, at which time I can get funding for any repairs for emissions failure. . If the converter is damaged, it's more commonly caused by engine performance problems (misfires, rich air-fuel mixture) or other serious issues that allow contamination (coolant and engine oil) to reach the exhaust system.

The wavelength converter absorbs transmitted infrared radiation, heats up to 500 - 600°C and then radiates back medium- and long wave radiation. This test is done directly at the exhaust system; to detect a plugged catalytic converter or muffler or pipe. The exhaust system is designed to have about 3 psi maximum of An little effort. The converter may also get contaminated by engine emissions containing lead, sulphur, silicon or manganese. The average human skin temperature is 91 degrees Fahrenheit. Sensor 1 and Sensor 2 might also be called the upstream and downstream catalyst temperature sensors, respectively. lift the car if you can't get to the converter easily. dried brush to avoid a fire hazard from the heated exhaust system. A trouble code doesn't necessarily mean the expensive converter needs to be replaced; you need to do some troubleshooting before you decide. See if there's a difference in engine performance. A P0420 code means there's a problem with the catalytic converter not working at peak efficiency, and emissions will be out of spec as a result. Cat code still comes up and sometimes a misfire code comes up soon after. Aug 21, 2010. The likely issue is that the catalytic converter has clogged, restricting gas flow.
