2.7.7.6. Control lamp of malfunction

The control lamp of malfunction (control lamp of malfunction of a control system of the engine) lights up or on the HI-SCAN device diagnostic codes of malfunctions in the following cases are removed:
1. During 0,1 from later inclusion of ignition pressure in the inlet pipeline less than 118 Mbar.
2. With a frequency of rotation of a bent shaft 1980 min.-1 pressure in the inlet pipeline less than 118 Mbar are lower.
3. At the released accelerator pedal pressure in the inlet pipeline not less than 986 Mbar, and the frequency of rotation of a bent shaft is not lower than 2400 min.-1 (as though the car moved down a bias).

Fig. 2.239. Socket of the sensor of absolute pressure


Check tension on conclusions of 1 and 4 electric sockets of the sensor of the absolute pressure (fig. 2.239).
Conclusion 4: "mass" of the sensor of absolute pressure.
Conclusion 1: exit of the sensor of absolute pressure.
At tension deviation from norm replace the sensor of absolute pressure
