  "textContent": "In the activation determining system for an oxygen sensor, 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 falls in a predetermined deactivation range Rna including the convergence value VP. The deactivation determining section is configured to determine that the oxygen sensor is in an activated state when the output value Vd(n) falls in a predetermined first activation range Ra1 different from the deactivation range Rna. The deactivation determining section is configured to determine that the oxygen sensor is in the deactivated state when the output value Vd (n) varies towards the convergence value VP and exceeds a predetermined threshold Vth including in the first activation range Ra1 during execution of fuel supply cut-off.",
