2.5.3.18. Control system of air hashingJamming in a closed position of the gate of system of hashing of air (P2006)
The PCM block controls the size of a mass consumption of air. If the actual size of a consumption of air of a stream – below estimated size, then, under following conditions, the PCM block considers that the gate of system of hashing of air is blocked in a closed position:
– frequency of rotation of the engine – is higher than 3750 min.-1;
– temperature of cooling liquid of the engine – is above 63 °C;
– the angle of opening of a butterfly valve – is more threshold значения*.
* The maximum calculated value of loading changes depending on the frequency of rotation of the engine
Low level of an entrance signal of a chain of the electromagnetic valve of management of system of hashing of air (P2009)
The PCM block controls the variable operating signal of the electromagnetic valve of system on a conclusion 4T of the PCM block. If the PCM block switches off the electromagnetic valve, but tension on a conclusion 4T remains low, then he considers that the chain of the electromagnetic valve of management of system of hashing of air has malfunction.
High level of an entrance signal of a chain of the electromagnetic valve of management of system of hashing of air (P2010)
The PCM block controls the variable operating signal of the electromagnetic valve of system on a conclusion 4T of the PCM block. If the PCM block turns on the electromagnetic valve, but tension on a conclusion 4T remains high, the PCM block considers that the chain of the electromagnetic valve of management of system of hashing of air has malfunction.
