1. An emission control system comprising:

  • an emission control device having a plurality of passages to facilitate emission control of an exhaust gas from a vehicle engine;

    an electromagnetic field generator that responds to a control signal by generating an electromagnetic field via a coil to inductively heat the emission control device; and

    a controller, coupled to the electromagnetic field generator, that generates a temperature signal indicating at least one temperature of the emission control device based on a change in inductance in the coil and that generates the control signal based on the temperature signal and further based on a reference temperature to control the at least one temperature of the emission control device in accordance with the reference temperature.
