INTAKE AIR TEMPERATURE SENSOR CHECK



 1.Disconnect the air flow sensor connector.
2.Measure the resistance between terminals No. 1 and No.4 of the air flow sensor connector.
Standard value:
    13 - 17 kΩ (at -20°C)
    5.4 - 6.6 kΩ (at 0°C)
    2.3 - 3.0 kΩ (at 20°C)
    1.0 - 1.5 kΩ (at 40°C)
    0.56 - 0.76 kΩ (at 60°C)
    0.31 - 0.43 kΩ (at 80°C)

3.Measure resistance while heating the sensor using a hair drier.
Normal condition:
Temperature (°C)
 Resistance (kΩ)
Higher
 Smaller
4.If the value deviates from the standard value or the resistance remains unchanged, replace the air flow sensor assembly.
