Abstract: A sensor control apparatus supplies a constant current to an oxygen concentration detection cell when it judges that oxygen concentration is greater than 15% (the concentration of oxygen contained in a measurement chamber is high).

The sensor control apparatus detects a second difference voltage generated in the oxygen concentration detection cell as a result of the flow of the constant current to the oxygen concentration detection cell after a second detection time, which is previously set to be longer than the first detection time, following the supply of the constant current.

The deterioration determination section determines whether or not the oxidation catalyst has deteriorated, on the basis of the concentration of the flammable gas computed by the concentration computation section.

Abstract: A microcomputer calculates the concentration of ammonia contained in exhaust gas. The microcomputer repeatedly obtains from a first ammonia detection section a first ammonia electromotive force EMF1 whose value changes with both the concentrations of ammonia and a flammable gas contained in the exhaust gas. The microcomputer outputs, as ammonia concentration information at the present point in time, ammonia concentration information representing the ammonia concentration at the point 0.5 sec prior to the present point in time. The microcomputer sets a rich spike flag Fs when a first ammonia electromotive force change amount ?EMF1 is smaller than a value obtained by multiplying a start determination value by ?1. When the rich spike flag Fs is set, the microcomputer sets the ammonia concentration information at the present point in time to the value of the ammonia concentration information at the point immediately before the rich spike flag Fs is set.
