Measuring instrument of a consumption of air (Air flow sensor – AFS)
Measuring instrument of a consumption of air with a heated-up thin film, the micromechanical which measuring system registers a stream of air and its direction.
The sensor of temperature of air arriving in the engine is built in the sensor of a measuring instrument of a consumption of air and represents a termistor which resistance changes depending on temperature.
Sensor check
PERFORMANCE ORDER
Using an ohmmeter, measure resistance of the sensor of temperature of air arriving in the engine.
Measure resistance between plugs of the socket of the sensor.
Temperature
Resistance, kiloohm
0°C
5,12–5,89
20°C
2,29–2,55
40°C
1,09–1,24
80°C
0,31–0,37
If resistance of the sensor differs from demanded, replace the sensor together with AFS.
