Idle speed correction depending on the battery voltage and on the balance of electrical energy
The engine idle speed correction compensates for the voltage drop when the electrical consumer is switched on if the battery is weakly charged. The correction starts when the voltage becomes less than 12 V. As a result of the correction, the engine speed can be increased to no more than 1500 min-1.
Communication between power steering pressure switch and injection computer
The injection ECU receives information from the power steering pressure switch and can raise the idle speed to compensate for power consumption.
Idling speed is brought to 720 min-1, if the vehicle speed is below 5 km/h.
Correction of turns of the idling engine at malfunction of the gauge of position of a pedal of an accelerator
If there is no signal from both conductive tracks of the accelerator pedal position sensor, the engine speed is brought to approximately 1200 min-1.
Idle speed correction in the event of a malfunction of the throttle valve with servo
If there is no signal from both conductive paths of the throttle position sensor, the throttle valve unit switches to the mode of mechanical restriction of the throttle opening. In this case, the engine runs at 900-1400 rpm-1.
