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

Fig. 25 Intake Air Thermo Sensor (Dynamic Chamber):

1. Disconnect intake air thermo sensor connector.
2. Connect ohmmeter to sensor terminals Fig. 25.
3. Check resistance of sensor. There should be 37.3-45.6k ohms at 68°F, 10.5-12.9k ohms at 122°F and 3.1-3.8k ohms at 185°F.
