2.5.3.19. Sensor of barometric pressure

Low level of an entrance signal of a chain of the sensor of the barometric pressure (P2228)

The PCM block controls the entrance tension of the sensor of barometric pressure. If entrance tension on a conclusion 1G of the PCM block – lower than 0,35 In, the PCM block considers that the chain of the sensor of barometric pressure has malfunction.

High level of an entrance signal of a chain of the sensor of the barometric pressure (P2229)

The PCM block controls the entrance tension of the sensor of barometric pressure. If entrance tension on a conclusion 1G of the PCM block – higher than 4,92 In, the PCM block considers that the chain of the sensor of barometric pressure has malfunction.
