Examination
Remove the sensor (without unplugging).
Turn the ignition key to the ON position, blow air from the air cleaner housing side and check the change in the output voltage between sensor pin #1 and «weight».
- Air does not enter: approx. 1V
- With air supply: approx. 1.5V (The more airflow, the higher the voltage).
Note: When blowing air from the duct side, the voltage decreases.
Removing
1. Disconnect the connector.
2. Remove the upper air cleaner housing with the mass air flow sensor.
3. Remove the sensor from the upper air cleaner housing.
