Code P1100 2007 Ford Fusion Description

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). If during the last 40 warm-up cycles in key ON engine running the PCM detects a voltage (or air flow) change beyond the minimum or maximum calibrated limit, a continuous memory Diagnostic Trouble Code (DTC) P1100 is stored.
