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.
P0103 - MASS OR VOLUME AIR FLOW A CIRCUIT HIGH INPUT
| Description: | The mass air flow (MAF) sensor circuit is monitored by the PCM for high air flow (or voltage) input through the comprehensive component monitor (CCM). If during KOEO, or KOER, the air flow (or voltage) changes above a maximum calibrated limit, the test fails. | ||
| Possible Causes: |
|
||
| Diagnostic Aids: | A MAF V PID (MAF PID) reading greater than 4.6 volts during KOER indicates a concern. | ||
| Application | Key On Engine Off | Key On Engine Running | Continuous Memory |
| All | GO to PINPOINT TEST DC . | ||
