STEP 4. Check harness between C-103 (terminal 
No. 115) engine-ECU connector and A-45 
(terminal No. 6) EGR valve assembly connector.

• Check output line for open/short circuit and dam-

age.

Q: Is the check result normal?

YES : 

Go to Step 5 .

NO : 

Repair the damaged harness wire.

STEP 5. Check harness between C-103 (terminal 
No. 130) engine-ECU connector and A-45 
(terminal No. 4) EGR valve connector.

• Check output line for open/short circuit and dam-

age.

Q: Is the check result normal?

YES : 

Go to Step 6 .

NO : 

Repair the damaged harness wire.

STEP 6. M.U.T.-III diagnosis code

YES : 

Replace the engine-ECU. When the engine-

ECU is replaced, write the chassis number 
(Refer to GROUP 00 

− Precautions Before 

Service 

− How to Perform Chassis Number 

Writing ). After replacing the engine-ECU, 
register the injector identification code and 
learn fuel injection (Refer to GROUP 00 

− 

Precautions Before Service 

− What The 

Common Rail Engine Learns ). After 
registering the injector identification code, 
the vehicle equipped with the DPF carries 
out the forcible DPF regeneration. (Refer to 
GROUP 17 

− Emission Control − Diesel 

Particulate Filter (DPF) System 

− Forcible 

DPF Regeneration ).

NO : 

Intermittent malfunction (Refer to GROUP 
00 

− How to Use Troubleshooting/

Inspection Service Points 

− How to Cope 

with Intermittent Malfunctions ).

Code No. P0405: EGR Valve Position Sensor Circuit Low Input <Except Euro5>

OPERATION

• A power voltage of 5 V is applied to the EGR 

valve assembly power terminal (terminal No. 3) 
from the engine-ECU (terminal No. 71) and 
earthed to the engine-ECU (terminal No. 81) from 
the EGR valve assembly (terminal No. 2).

• The sensor signal is inputted to the engine-ECU 

(terminal No. 57) from the EGR valve assembly 
output terminal (terminal No. 1).

FUNCTION

• The EGR valve assembly detects the position of 

the EGR valve and sends the signal to the 
engine-ECU.

• Based on the signal, the engine-ECU performs 

the feedback control of the EGR valve.

TROUBLE JUDGMENT

Check Conditions

• Battery positive voltage is 8 − 16 V

• 2 seconds later after the ignition switch has been 

in "ON" position or the engine has started up.

Judgment Criterion

• The EGR valve position sensor output voltage is 

0.20 V or less for 0.5 second.

PROBABLE CAUSES

• Failed EGR valve position sensor

• Open/short circuit or harness damage in EGR 

valve position sensor circuit or loose connector 
contact

• Failed engine-ECU

− How to Cope 

with Intermittent Malfunctions ).

NO : 

Go to Step 2 .

STEP 2. Connector check: A-45 EGR valve 
assembly connector

Q: Is the check result normal?

YES : 

Go to Step 3 .

NO : 

Repair or replace the connector.

STEP 3. Perform voltage measurement at A-45 
EGR valve assembly connector.

• Disconnect connector, and measure at harness 

side.

• Ignition switch: ON

• Voltage between terminal No. 3 and earth.

OK: 4.9 

 5.1 V

Q: Is the check result normal?

YES : 

Go to Step 9 . 

NO : 

Go to Step 4

engine-ECU connector.

• Measure engine-ECU terminal voltage.

• Ignition switch: ON

• Voltage between terminal No. 71 and earth.

OK: 4.9 

 5.1 V
