What is the "exhaust system overheat" light for?

The "exhaust system overheat" light is connected to a temperature sensor
inside the car, under the carpeting, by the passenger seat. The
location of this sensor is just above the main catalytic converter, and
its purpose is to warn of excessive heat being generated by the converter.
When the temperature of the passenger floor reaches about 220 degrees F,
the ECU activates the relief air bypass and bleeds off air that would
otherwise go to the catalytic converter. This has the effect of cooling
the catalytic converter.
