Possible Causes
NOTE:
Circuit references IATS G_G_IATS
- The engine control module measured a signal voltage above a specified range but not necessarily a short circuit to power, gain too high
- Mass air flow sensor connector is not correctly latched
- Power feed to mass air flow sensor, open circuit
- Mass air flow sensor circuit, short circuit to ground, short circuit to power, open circuit, high resistance
- Mass air flow sensor failure
