CIRCUIT - SYSTEM SCHEMATIC DIAGRAM 61-45

System description:
The engine management system consists of sensor signal input, electronic control module
and actuation control.
Signal input 61
Engine oil pressure switch
With the engine started, if the engine oil pressure is high and the engine oil pressure switch
is disconnected, the engine ECU will send a signal to the instrument cluster via the CAN
line, with the engine oil pressure warning lamp on the instrument cluster extinguished.
Crankshaft Position Sensor And Camshaft Position Sensor
Combination the two points to judge the position of the crankshaft and camshaft, supply
ignition timing.
Rail Pressure Sensor
Supply ECU to the engine, the common rail inside pressure signal.
Fuel Injector And Fuel Metering Unit
Respectively control the fuel quantity injected into the cylinder and the common rail.
Electronic Accelerator Pedal Sensor
Electronic accelerator pedal sensor detects the accelerator pedal position, when it
detects a change of the accelerator pedal position, it will instantly transmit the changing
information to the engine electronic control module, the engine electronic control module
will process the information, which is considered as a basic signal of adjusting the fuel
quantity injection.
Installation position: at the accelerator pedal.
