Abstract:
A method includes providing electric power to an electrically heated catalyst of an exhaust aftertreatment system. The method includes obtaining an impedance value of the electrically heated catalyst in response to providing the electric power. The method includes determining an oxygen storage capacity of the electrically heated catalyst based on the impedance value.
