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:

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.
