Component Tests and General Diagnostics
1. Disconnect connector from air flow meter.
2. Measure resistance between sensor terminals 1 and 4 (outer terminals).
3. Resistance should be:
8250 - 10,560 ohms at -9 - -11°C (12 - 16°F)
2280 - 2780 ohms at 19 - 21°C (66 - 70°F)
750 - 910 ohms at 49 - 51°C (120 - 124°F)
4. If resistance values are not within specifications, temperature sensor is defective.
Note: Air temperature sensor is integral with the air flow meter and cannot be serviced separately. If sensor is defective, air flow meter must be replaced.
