Refer to DTC P0602.

DTC DESCRIPTION

E0AEAC1F

P0606 is set when 1) writing/reading error inside of ECM occur. 2) error of APS 2 ground checking which is repeated
every 0.2 sec. or 3) the voltage of sensor power supply 1 and 2 ( the standard voltage of A/D converter) are below 4.7V
or above 5.1V. This code is due to ECM internal failure.

APS 2 Ground check signal

APS 1 Signal

APS 2 Signal

Fig.1

Fig.2

Fig.1) Ground checking signal of APS 2 signal is for ECM to monitor APS 2. This signal drops APS 2 output voltage to below
          200.39mV every 200msec. If APS 2 output voltage does not drop  to below 200.39mV, ECM sets DTC as recognizing ground
          circuit error of APS 2 .

 The waveform below 200.39mV is not detectable in ground checking signal waveform of APS 2 signal. Instead, the waveform 

     which drops a little is detected. If APS 2 data of "SERVICE DATA" on the Scantool varies from 350mV to 0mV periodically, 
     it means it works normally.

Fig.2) APS 1 and APS 2 signals are measured simultaneously,  Check if 5V sensor voltage(the standard voltage of A/D converter
          inside of ECM) is from 4.8V to 5.16V.

COMPONENT LOCATION

E2C338B1

EGNG008C

GENERAL DESCRIPTION

E8583E16

Injectors spray fuel in the highly compressed combustion chamber, and power generates through combustion process.Fuel
pressure is raised to 1600bar in common rail diesel engine for the purpose of making fuel into minute particles. And fuel
devided into minute particles leads smoke reduction, high power generation, and improved fuel efficiency. To control
pressure of 1600bar with solenoid, oil pressure surbo is applied. And injector solenoids is actuated by solenoid oper-
ating voltage raised to 80V with the method of current control. Niddle valve inside of injector is located between A and
B chamber. If applied pressure to B chamber is relived by injector solenoid, niddle valve is raised by the pressure of A
chamber then, fuel is injected. If same pressure is applied to A and B chamber, niddle valve closes by the elasticity then,
fuel injection stops.As electronically controlled injector is applied instead of mechanical injector, pilot and post injection,
injeciton duration and quantity control are achieved. And engine performance is improved by these control.
