Abstract
A sensor probe having a first sensing element and a second sensing element. The first sensing element generates current changes in response to changes in a relative amount of a target element present in reference air versus a first exhaust gas chamber of the sensor probe. A second sensing element generates current changes in response to changes in a relative amount of the target element present in the first exhaust gas chamber and either a second exhaust gas chamber of the sensor probe or reference air.
