The engine control module (ECM) uses information from the crankshaft position (CKP) sensor and the camshaft position (CMP)
sensors to determine when an engine misre is occurring. By monitoring variations in the crankshaft rotation speed for each cylinder
ECM is able to detect individual misre events. When a misfire happens, unburnt mixture will be discharged into the exhaust system
and burnt in the exhaust system. A misre rate that is high enough can cause 3-way catalytic converter damage. The malfunction
indicator lamp (MIL) will ash ON and OFF when the conditions for catalytic converter damage are present. A DTC will be set.

Under stable operating
conditions, ECM detects the
crankshaft rotation speed
fluctuations.
Under stable operating conditions,
when ECM detect fluctuations in the
crankshaft rotation speed exceeds
the preset threshold value and when
a mild misfire occurs, there is no
emergency control programs.
System only records the DTC code
and data flow, and malfunction lamp
light. When there a serious misfire,
the system will be forced into the
open-loop control mode, and the
oxygen sensor learn is not allowed.
The malfunction lamp will flash at 1
Hz frequency.
