What Happens If You Start A Car Without Mass Air Flow Sensor? [Solved]

Without a proper signal from the mass air flow sensor, the powertrain control module (PCM), which manages the engine, transmission, and other systems in your car, won’t know how much fuel the engine needs. This can either cause the engine to run too lean (too little fuel) or too rich (too much fuel).
