P1101 - Mass Air Flow (MAF) Sensor Out Of Self-Test Range
WARNING: This page is about a different car, the 2010 Mercury Mariner and 2010 Ford Escape. 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 of 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 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 |
