2.5.3.9. Monitoring of the admission of ignition

The casual admission of ignition (P0300) is found, the ignition admission in the cylinder (by P0301, P0302, P0303, P0304) is found
The PCM block supervises a time interval of an entrance signal of the sensor of position of the crankshaft. The PCM block calculates change of a time interval for each cylinder. If change of a time interval exceeds previously the programmed values, the PCM block finds the ignition admission in the corresponding cylinder. In engine operating time the PCM block considers number of admissions of ignition which occurred for each 200 and 1000 turns of a cranked shaft, and calculates factor of the admission of ignition for each turn of a cranked shaft. If the relation exceeds previously the programmed values, the PCM block decides that there was an admission of ignition which can lead to damage of catalytic converter or influence characteristics of emissions.
