Code P1101 2007 Ford Fusion Description

The Mass Air Flow (MAF sensor circuit is monitored by the Powertrain Control Module (PCM) for an out of range air flow (or voltage) input. If during key ON engine OFF the air flow voltage signal is greater than 0.27 volts the test fails. Likewise, if during key ON engine running, an air flow voltage signal is not within 0.46 volt to 2.44 volts, the test fails.
