INTAKE AIR TEMPERATURE SENSOR CHECK
1. Disconnect the air flow sensor connector.
2. Measure resistance between terminals 5 and 6.
Standard value:
2.3 - 3.0 k
W
(at 20
_
C)
0.26 - 0.36 k
W
(at 80
_
C)
3. Measure resistance while heating the sensor using a hair
drier.
Normal condition:
Temperature ( _ C) Resistance (k W )
Higher Smaller
4. If the value deviates from the standard value or the
resistance remains unchanged, replace the air flow sensor
assembly.
