What is catalyst temperature?
What is catalyst temperature? Exhaust catalysts usually operate in the temperature range 150–600 °C, but they can experience temperatures of up to 1000 °C. The conditions that can produce such high temperatures include repeated misfire (resulting in the oxidation of large amounts of unburned fuel over the catalyst) and high driving speeds. What is a good catalytic converter temp? The average light off temperature at which a catalytic converter begins to function ranges from 400 to 600 degrees F. The normal operating temperature can range up to 1,200 to 1,600 degrees F. What causes a catalyst monitor to set code...
