Air Temperature Sensor ( Ambient / Intake ): Testing and Inspection

AIR TEMPERATURE SENSOR RESISTANCE TEST

1. Disconnect the intake air temperature sensor connector.




2. Measure resistance between terminals 1 and 2.

Standard value:
2.3 - 3.0 kohms at 20°C (68°F)
0.30 - 0.42 kohms at 80°C (176°F)

3. Remove the intake air temperature sensor.




4. Measure resistance while heating the sensor using a hair dryer.




Normal condition

5. If the value deviates from the standard value or the resistance remains unchanged, replace the intake air temperature sensor.
6. Install the intake air temperature sensor and tighten it to the specified torque.

Tightening torque: 12 - 15 Nm (9 - 11 ft.lbs.)
