Abstract
Various systems and methods are provided for an exhaust gas treatment system. In one example, a system includes an exhaust gas treatment device and a wire wrapped around an exterior circumference of the exhaust gas treatment device. Continuity of the wire is monitored such that degradation of the wire due to degradation of the exhaust gas treatment device is indicated.
