Abstract: A short-circuit pinpointing device for testing a wide-range air/fuel sensor includes a current-sink and a controller. The current-sink is selectively connectable to one or more of sensor-terminals of a wide-range air/fuel sensor that include a reference-terminal, a pump-terminal, a return-terminal, and a tag-terminal. The controller is in communication with the current-sink and the sensor-terminals. The controller controls the connection of the current-sink to the one or more sensor-terminals. The controller also determines one or more status-values based on signals present at the sensor-terminals. The controller also determines a sensor-status of the wide-range air/fuel sensor based on the connection of the current-sink and the one or more status-values.

Abstract: A method includes, responsive to an application of power to an IC, self-initializing the IC by asserting a reset signal for a reset period. Self-initializing the IC also includes, in response to an expiration of the reset period, deasserting the reset signal. Self-initializing the IC also includes, responsive to deasserting the reset signal, automatically obtaining first temperature data from at least one thermal sensing device associated with a die of the IC, and storing the first temperature data in a storage component of the IC.

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.
