A heater heats the oxygen sensor. A first voltage is applied to the oxygen sensor and the concentration of oxygen is detected based on a first output current from the oxygen sensor obtained when the first voltage is applied to the oxygen sensor. A second voltage is applied to the oxygen ...
A readily manufacturable heated solid electrolyte oxygen sensor. A heater subassembly readily adaptable to unheated oxygen sensor technology, provides a greater reference oxygen gas source to the reference electrode of the solid electrolyte body, in addition to being positioned and rigidly secured within...
In a heated type oxygen sensor having a sensing element responding to changes in the exhaust oxygen content and a heater inside, a diagnostic system for diagnosing deterioration of the heated type oxygen sensor comprises an electronic control unit being responsive to an engine temperature for ...
