Abstract
A method is proved for pinpointing a short-circuit in a wide-range air/fuel sensor having one or more sensor-terminals that include a reference-terminal, a pump-terminal, a return-terminal, and a tag-terminal. The method includes controlling a connection of a source of electric current to the one or more sensor-terminals; determining one or more status-values based on signals present at the sensor-terminals; and determining a sensor-status of the wide-range air/fuel sensor based on the connection of source of electric current and the one or more status-values.
