Disconnect air line 1 from the air flow meter and disconnect the meter connector (pic. 2-113). Connect an ohmmeter to the leads «3» and «4» meter pads and check the resistance. which should be in the range of 500-1100 ohms.
Connect an ohmmeter to the leads «2» and «4», «2» and «3» and manually move the pressure disk of the air flow meter. In this case, the resistance on the ohmmeter should change smoothly in the range of 8-2500 ohms.
