Air Flow Meter/Sensor: Adjustments
Airflow Sensor Arrangement
1.
Activate the fuel pumps for 5 seconds in order to zero the sensor plate position.
2.
Slip a (0.002in.) feeler gauge between the sensor plate and the cylindrical part of the air funnel.
^
The feeler gauge should be able to be slipped freely around the sensor plate. Recenter the plate if necessary.
^
The air-flow sensor plate should not bind even under slight, lateral pressure.
3.
Push down on the sensor plate slightly.
4.
Release the sensor plate.
^
The sensor plate should not bind when released and audibly touch the sensor plate stop bracket.
Air Flow Sensor Plate Position
5.
With the engine (OFF) visually inspect the air-flow sensor plate position (vertical) within the air funnel.
^
The air-flow sensor plate upper edge must stand flush with the upper edge of the cylindrical part of the air funnel. A higher position of up to
0.008 in. (0.2mm) is permissible. Adjust the zero point if necessary.
