DTC P1101: Mass Air Flow (MAF) Sensor Out Of Self-Test Range
WARNING: This page is about a different car, the 2011 Mercury Milan, 2011 Lincoln MKZ, 2011 Ford Fusion, 2010 Mercury Milan, and 2010 Ford Fusion. 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 powertrain control module (PCM) for an out f range air flow (or voltage) input. If, during key ON engine OFF (KOEO), the air flow voltage signal is greater than 0.27 volt the test fails. Likewise, if, during key ON, engine running (KOER), the air flow voltage signal is not within 0.46 volt to 2.44 volts, the test fails. | ||
| Possible Causes: |
|
||
| Diagnostic Aids: | A MAF V parameter identification (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 concern. | ||
| Application | Key On Engine Off | Key On Engine Running | Continuous Memory |
| All | GO to PINPOINT TEST DC . | ||
