DTC P1101: Mass Air Flow (MAF) Sensor Out of Self-Test Range
WARNING: This page does not describe the selected car, but rather 32 other vehicles, including the 2005 Mercury Sable, 2005 Mercury Mountaineer, 2005 Mercury Monterey, 2005 Mercury Montego, and 2005 Mercury Mariner. 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 hard fault. | ||
| Application | Key On Engine Off | Key On Engine Running | Continuous Memory |
