5.7. The sensor of absolute pressure in an inlet collector (MAF) with the IAT sensor

The sensor of absolute pressure in an inlet collector represents the sensitive resistor. It measures pressure in an inlet collector which changes depending on operational modes of the engine and is transformed to tension. The sensor also is used for measurement of atmospheric pressure at start of the engine and provides power setting at different heights above sea level. On the basis of information from the sensor the control unit the engine regulates amount of fuel submitted to the engine, and also changes a corner of an advancing of ignition.

 PERFORMANCE ORDER

1. Connect the voltmeter between plugs 1 and 4 of the socket of the sensor.

2. Measure tension.

  • Target tension at the included ignition and the idle engine: 4–5 In
  • Target tension on frequency of idling: 0,5–2,0 In

3. If target tension of the sensor differs from demanded, replace the sensor.
