Air Flow Meter/Sensor: Testing and Inspection
INSPECTION
NOTICE: Do not drop or subject the sensor to shock. Do not put objects inside the sensor.
1. Disconnect the mass air flow sensor connector.
2. Loosen air intake hose retaining clamps on both sides of the mass air flow sensor.
3. Disconnect the air intake hose from the mass air flow sensor.
4. Remove the two bolts attaching the mass air flow sensor to the mounting bracket.
5. Remove the mass air flow sensor.
6. Check mass air flow sensor for damage, replace if necessary.
7. Attach mass air flow sensor to air intake hose and to the mounting bracket.
8. Replace the two bolts to retain the mass air flow sensor to the mounting bracket.
Tighten bolts to 69 - 96.3 lb-in (7.8 - 10.8 N.m).
9. Reconnect the air intake hose to the mass air flow sensor.
10. Tighten the bolts of the retaining clamps on both sides of the mass air flow sensor.
11. Reconnect the mass air flow sensor connector to the sensor.
12. Warm up the engine to normal operating temperature and let it idle.
13. Connect a voltmeter between terminal 4 (RED/GRN wire) and ground.
14. Verify that the voltage varies between 0.8V - 1.2V.
15. Rev up the engine and verify that voltage varies between 3.5V - 4V.
16. If the voltage is not within specification, replace the mass air flow sensor.
