Check of a condition and replacement of the sensor of absolute pressure in the pipeline (MAR) On models since 1996 вып. the sensor of absolute pressure in the pipeline complete with the MAR electromagnetic valve is used for tracking depth of depression in the inlet pipeline. Change of this parameter of rather barometric pressure grows out of changes of the current load of the engine and its turns. RSM uses signals arriving from the MAR sensor in the diagnostic purposes. At delivery by the module of management of tension on the MAR electromagnetic valve the last provides development of the vacuum signal switching the MAR sensor to measurement of barometric pressure. In the absence of tension on the valve the MAR sensor makes reading of depth of depression in the pipeline which any change will be transformed to the alarm tension right there transferred to RSM. The amplitude of a signal developed by the sensor can change in a range from 0.5 In at completely closed butterfly valve, to 5.0 In at completely open (low depth of depression). Also certain dependence of amplitude of a signal developed by the sensor on the barometric pressure defined by height of position of the car above sea level takes place. The sensor and the MAR electromagnetic valve are established on back (from transmission) an end face of the left (forward) head of cylinders. RSM distinguishes some types of violations of functioning of the sensor, to each of which OBD appropriates an individual code of malfunction.CHECK
