9. Sensor of temperature of liquid

Considered cars are equipped with several systems of decrease in toxicity of exhaust gases. Them treat:

  – onboard system diagnostics (OBD system);
  – control system of the engine (EFI system);
  – system retsirkulyatsiya (EGR system);
  – catching system паров gasoline (EVAP system);
  – system of compulsory ventilation of a case (PCV system);
  – system of a choice of the channel absorptions (ACIS system);
  – catalytic converter.
The concrete type of applied systems with the indication of adjusting data is specified on podkapotny plates (VECI plate).
