8.2.5. The sensor of the soaked-up air
The thermal sensor takes temperature of the soaked-up air. This size together with a signal of the sensor of pressure of the inlet gas pipeline (system of PMS management) serves as criterion for evaluation of amount of the let-in air. Tremodatchik of the soaked-up air is the NTC resistor (NTC – negative temperature coefficient) which resistance decreases at temperature increase. The thermal sensor is located on the left side of a cross pipe of the air filter. Removal
