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

Intake Air Thermosensor:

1. Remove sensor and connect ohmmeter across terminals.
2. Heat sensor and a thermometer with same source (such as a lamp) and measure sensor resistance:

^ 2.2 - 2.7K ohms @ 68°F (20°C)
^ 0.29 - 0.35K ohms @ 176°F (80°C)

3. If not as specified, replace sensor.
