  • Patent number: 11286833
    Abstract: A method includes providing electric power to an exhaust aftertreatment system component, where the exhaust aftertreatment system component is one of a particulate filter and an electrically heated catalyst. The method includes obtaining an impedance value of the exhaust aftertreatment system component in response to providing the electric power. The method includes determining a structural state of the exhaust aftertreatment system component based on the impedance value.
    Type: Grant
