Abstract
A catalytic converter protection system that includes a controller, a catalytic converter having a housing, and a shorting element that has two terminals and is coupled to the housing. The system also includes a connector having an internal resistor. The connector is electrically coupled to the controller and the two terminals. The controller monitors resistance of the internal resistor to determine continuity between the connector and the shorting element. The controller may activate an alarm element with a loss in continuity between the terminals and the shorting element.
