1.Disconnect the air flow
sensor connector. 2.Measure resistance between
terminals No. 1 and No. 4. Standard
value:
13 - 17 kΩ (at
-20°C) 5.3 - 6.7 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) 0.30 - 0.45 kΩ (at
80°C)
3.Remove the air flow
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 air flow sensor assembly. 6.Install the air
flow sensor and tighten it to the specified
torque. Tightening torque: 1.8 ± 0.6
