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.
