Mass or Volume Air Flow Circuit Low Input (P0102,P0103)
DESCRIPTION
The mass air flow meter is a sensor that measures the amount of air flowing through
the throttle valve. The ECM uses this information to determine the fuel injection
time and to provide the appropriate air-fuel ratio.
Inside the mass air flow ...
