Abstract: A constant current circuit is controlled to stop a constant current Ics (Ics=0) flowing between sensor electrodes of an oxygen sensor, in a period before the oxygen sensor becomes active, during a fuel cut of an engine, and after the engine stops. When an abnormality (for example, a failure) occurs in the constant current circuit, a sensor output equivalent to an output of the oxygen sensor of when the constant current circuit is controlled to stop the constant current Ics is different from a normal sensor output. An abnormality diagnosis is executed to determine a presence or absence of the abnormality in the constant current circuit depending on whether the output of the oxygen sensor is out of a predetermined normal range, in a period before the oxygen sensor becomes active, during a fuel cut of an engine, and after the engine stops (when the constant current circuit is controlled to stop the constant current Ics).

Abstract: A system for testing a pressure sensor of a seat includes a loading device and a processor. The loading device removably applies weight to the seat. The processor receives a measurement of a pre-installation pressure offset of a bladder of the pressure sensor measured before installation of the pressure sensing assembly into the seat. The processor is programmed to receive a weighted measurement from the pressure sensor in the seat when the loading device applies weight to the seat and an empty seat measurement from the pressure sensor in the seat when the loading device does not apply weight to the seat. The processor determines a threshold value by subtracting the empty seat measurement from the weighted measurement. The processor determines a seat pressure offset value by subtracting the pre-installation pressure offset value from the threshold value. The processor compares the seat pressure offset value to a selected range.
