P1100 2007 Ford Fusion Code - Mass Air Flow Sensor Intermittent
Quick Answer
The Mass Air Flow (MAF) Sensor circuit is monitored by the Powertrain Control Module (PCM) for sudden voltage (or air flow) input change through the Comprehensive Component Monitor (CCM). Common causes include Faulty Mass Air Flow Sensor, Air leak before or after sensor, Mass Air Flow Sensor harness is open or shorted. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.
