Ignition key (turning on the power of the devices)
When the ignition is turned on, a voltage signal is transmitted to the ECM to turn on the control system power relay.
Egnition lock (starter activation)
The voltage from the ignition switch is transmitted to the ECM, signaling the operation of the starter. The ECM generates the optimal combination of output parameters for the starting mode.
Vehicle speed sensor
The sensor signal is used to determine the amount of injected fuel.
Atmospheric pressure sensor
The sensor signal is used to correct the amount of injected fuel.
Air conditioner switch
Sends a signal to the ECM to turn on / off the air conditioner.
Load signal from A/C compressor
The sensor signal is used to correct 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.
1st gear signal (manual transmission)
Based on the signal from this sensor, the ECM adjusts the engine speed.
Reverse signal (manual transmission)
Based on the signal from this sensor, the ECM adjusts the engine speed.
