2.5.3.4. Pressure sensor in an inlet collector

The signal of the sensor of a mass consumption of air will not be coordinated with a signal of the sensor of provision of a butterfly valve (P0101)
The PCM block compares the actual entrance signal from pressure sensor in an inlet collector to the expected entrance signal from pressure sensor in an inlet collector (calculated on entrance tension from the sensor of provision of a butterfly valve or frequency of rotation of the engine).
If the size of a mass consumption of air on an admission – is lower than 5,0 g / page during 5 with, and the angle of opening of a butterfly valve – more than 50% at the working engine, the PCM block decides that the found size of a mass consumption of air on an admission is too small.
If the size of a mass consumption of air on an admission – is higher than 96,5 g / page during 5 with, and the frequency of rotation of the engine – is lower than 2000 min.-1, the PCM block decides that the found size of a mass consumption of air on an admission is too big.

High level of an entrance signal of a chain of the sensor of pressure of air in an inlet collector (P0102)
The PCM block controls entrance tension from pressure sensor in an inlet collector at the working engine. If entrance tension on a conclusion 1P of the PCM block – lower than 0,21 In, the PCM block decides that pressure chain in an inlet collector has malfunction.

High level of an entrance signal of a chain of the sensor of pressure of air in an inlet collector (P0103)
The PCM block controls entrance tension from pressure sensor in an inlet collector at the working engine. If entrance tension in a conclusion 1P of the PCM block – higher than 4,9 In, the PCM block decides that pressure chain in an inlet collector has malfunction.
