Intake Air Temperature Sensor: Testing and Inspection
Intake Air Temperature Sensor
To test the Intake Air Temperature Sensor, located on the air flow sensor, in the air cleaner housing. Remove the air flow sensor (AFS) connector
and proceed as follows.
COMPONENT TEST
1.
Measure the resistance between terminals 5 and 6.
Terminal 6: Intake air temperature output
Terminal 5: Sensor ground
Standard Values
6.0 ohms at 32° F
2.7 ohms at 68° F
0.4 ohms at 176° F
Intake Air Temperature Sensor Testing
2.
Measure the resistance while heating the sensor using a hair drier. You should observe a reduction in resistance (less Ohms) in response to an
increase in temperature at the sensor.
3.
If the value deviates from the standard value or the resistance remains unchanged, replace the air flow sensor assembly.
