1. Disconnect the EGR gas temperature sensor 

connector.

2. Measure resistance between terminals No. 1 and 

No. 2.

Standard value:

55 

− 78 kΩ (at −20°C)

29 

− 41 kΩ (at 0°C)

17 

− 23 kΩ (at 20°C)

10 

− 14 kΩ (at 40°C)

7.1 

− 8.8 kΩ (at 60°C)

4.8 

− 5.9 kΩ (at 80°C)

3. Remove the EGR gas temperature sensor

4. Measure resistance while heating the sensor 

using a hair drier.

Normal condition:

Temperature (

°C)

Resistance (k

Ω)

Higher

Smaller

5. If the value deviates from the standard value or 

the resistance remains unchanged, replace the 
EGR gas temperature sensor.

6. Install the EGR gas temperature sensor and 

tighten it to the specified torque.

Tightening torque: 20 

± 4 N⋅m

DIESEL PARTICULATE FILTER (DPF) 
SYSTEM <Euro5>

GENERAL INFORMATION (DIESEL 
PARTICULATE FILTER SYSTEM)

M1175006600261

The Diesel Particulate Filter (DPF) system is used to 
adsorb and remove the Particulate Matter (PM) con-
tained in the exhaust gas. The engine-ECU antici-
pates the amount of PM accumulated in the DPF 
through the input signal from each sensor.
