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.
