  "textContent": "In an activation determining system, a signal processing circuit is configured to output a signal converging to a predetermined convergence value VP when the oxygen sensor is maintained in the deactivated state. A deactivation determining section is configured to determine that the oxygen sensor is in the deactivated state when an output value Vd (n) from the signal processing circuit varies towards the convergence value VP for a predetermined period of time or longer during execution of fuel supply cut-off or when the output value Vd(n) varies towards the convergence value VP by a predetermined amount or greater during execution of the fuel supply cut-off.",
