EGR GAS TEMPERATURE SENSOR CHECK




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 (kΩ)
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
