Ignition switch (switching on the power supply of the devices)
When the ignition is turned on, a voltage signal is transmitted to the ECU to turn on the control system power relay.
Ignition switch (starter switch)
Voltage from the ignition switch is transmitted to the ECU, signaling the starter operation. The ECU generates the optimal combination of output parameters for the starting mode.
Vehicle speed sensor
The sensor signal is used to determine the amount of fuel to be injected.
Atmospheric pressure sensor
The sensor signal is used to correct the amount of fuel injected.
Air conditioner switch
Transmits a signal to the ECU to turn the air conditioner on/off.
Load signal from the air conditioner compressor
The sensor signal is used to adjust the idle speed depending on the mechanical resistance of the air conditioner.
Power Steering Pressure Sensor
The threshold sensor signals the pressure in the hydraulic power steering system.
First gear engagement signal (manual transmission)
(Original source of information: MitsubishiMan.ru)
Based on the signal from this sensor, the ECU adjusts the engine speed.
Reverse gear engagement signal (manual transmission)
Based on the signal from this sensor, the ECU adjusts the engine speed.
