Abstract: Various methods and system are described for determining ambient humidity via an exhaust gas sensor disposed in an exhaust system of an engine. In one example, a reference voltage of the sensor is modulated between a first and second voltage during non-fueling conditions of the engine. The ambient humidity is determined based on an average change in pumping current while the voltage is modulated.

Abstract: Methods and systems for an engine system including an exhaust gas sensor are disclosed. In one example, under a first engine fueling condition, an air-fuel ratio correction factor is determined based on an expected air-fuel ratio and an actual air-fuel ratio. During a second engine fueling condition and a third engine non-fueling condition, fuel alcohol content and ambient humidity, respectively, are determined based on the exhaust gas sensor and corrected based on the air-fuel ratio correction factor.

Abstract: Various systems and methods are described for an exhaust gas sensor coupled to an exhaust system of an engine. One example method comprises, during selected engine fueling conditions, alternating between applying first and second voltages to the sensor; and identifying an amount of alcohol in fuel injected to the engine based on sensor outputs at the first and second voltages.

Abstract: Various systems and methods are described for an exhaust gas sensor coupled to an exhaust system of an engine. One example method comprises, during selected engine fueling conditions, alternating between applying different voltages to the sensor; and identifying an amount of alcohol in fuel injected to the engine based on sensor outputs at the different voltages.
