1. Disconnect the mass airflow sensor connector.
2. Measure the resistance between terminal No. 4 and terminal No. 5.Standard value:
- 13 - 18 kΩ [at -20°C (-4°F)]
- 5.3 - 6.7 kΩ [at 0°C (32°F)]
- 2.3 - 3.0 kΩ [at 20°C (68°F)]
- 0.30 - 0.45 kΩ [at 80°C (176°F)]
3. If not within specifications, replace the mass airflow sensor.
4. Measure the resistance while heating the sensor using a hair dryer.Normal condition:
| TEMPERATURE | RESISTANCE (kΩ) |
| Higher | Smaller |
5. If the resistance does not decrease as heat increases, replace the mass airflow sensor.
