Air Temperature Sensor ( Ambient / Intake ): Testing and Inspection
INTAKE AIR TEMPERATURE (IAT) SENSOR (AIR CLEANER) INSPECTION1. Remove the IAT sensor (air cleaner).
2. Place the sensor and a thermometer in the water.
3. Gradually heat the water and measure the resistance of the sensor using an ohmmeter.
- If not as specified, replace the IAT sensor (air cleaner).

INTAKE AIR TEMPERATURE (IAT) SENSOR (DYNAMIC CHAMBER) INSPECTION
1. Remove the IAT sensor (dynamic chamber).
2. Place the sensor and a thermometer in the water.
3. Gradually heat the water and measure the resistance of the sensor using an ohmmeter.
- If not as specified, replace the IAT sensor (dynamic chamber).
Tightening torque: 7.9 - 11.7 N.m {80 - 120 kgf.cm, 70 - 104 in.lbf}

INTAKE AIR TEMPERATURE (IAT) SENSOR (L/C) INSPECTION
1. Remove the IAT sensor (L/C).
2. Place the sensor and a thermometer in the water.
3. Gradually heat the water and measure the resistance of the sensor using an ohmmeter.
- If not as specified, replace the AT sensor (L/C).
