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.
Specification:
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).
IAT Sensor Signal Characteristic (Reference):
