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

1. Disconnect the volume air flow sensor connectors.
2. Measure resistance between terminals 5 and 6.

Temperature [°C (°F)] Resistance

0 (32) 5.3-6.7 Ohms
20 (68) 2.3-3.0 Ohms
80 (176) 0.30-0.42 Ohms





3. Measure resistance while heating the sensor using a hair drier.

Temperature Resistance
Higher Smaller

4. if resistance does not decrease as heat increases the resistance remains unchanged, replace the volume air flow sensor assembly.
