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.
