Catalyst Damage

Within an interval of 200 crankshaft revolutions the detected number of misfiring events is calculated for each cylinder. The EMS2000 monitors this based on load/rpm. If the sum of cylinder misfire incidents exceeds a predetermined value, a "Catalyst Damaging" fault code is stored and the "Malfunction Indicator Light" will be illuminated.
If the cylinder misfire count exceeds the predetermined threshold the EMS2000 will take the following measures:
The oxygen sensor control will be switched to open loop.
The cylinder selective fault code is stored.
If more than one cylinder is misfiring the fault code for all individual cylinders and for multiple cylinders will be stored.
The fuel injector to the respective cylinder(s) is deactivated.
