  "textContent": "This control device for an internal combustion engine is equipped with: an air/fuel ratio sensor provided to the exhaust passage of an internal combustion engine; and an engine control device that controls the internal combustion engine according to the output of the air/fuel ratio sensor. The air/fuel ratio sensor is equipped with: a gas chamber to be measured, into which exhaust gas flows; a pump cell that pumps oxygen into or out of the gas chamber to be measured according to the pump current; and a reference cell of which the reference cell output current detected varies according to the air/fuel ratio inside the gas chamber to be measured. The reference cell is equipped with: a first electrode that is exposed to the exhaust gas in the gas chamber to be measured; a second electrode exposed to a reference atmosphere; and a solid electrolyte layer arranged between the electrodes. The air/fuel ratio sensor is equipped with: a reference cell voltage applying device that applies a sensor applied voltage between the electrodes; and a reference cell output current detection device that detects, as the reference cell output current, the current flowing between the electrodes.",
