P1101 - Mass Air Flow (MAF) Sensor Out Of Self-Test Range

WARNING: This page does not describe the selected car, but rather 30 other vehicles, including the 2004 Mercury Sable, 2004 Mercury Mountaineer, 2004 Mercury Monterey, 2004 Mercury Marauder, and 2004 Mercury Grand Marquis. However, it is still accessible from the selected car via links, so may be relevant.

P1101 - MASS AIR FLOW (MAF) SENSOR OUT OF SELF-TEST RANGE

Description:	The MAF sensor circuit is monitored by the 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 volt 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.
Possible Causes:	Low battery charge. MAF sensor partially connected. MAF sensor contamination. PWR GND open to the MAF sensor. MAF RTN circuit open to PCM. Damaged MAF sensor. Damaged PCM.
Diagnostic Aids:	A MAF V PID reading greater than 0.27 volt (KOEO) or a MAF V PID reading outside the 0.46 volt to 2.44 volts range (KOER) indicates a hard fault.
