P0103 - MASS OR VOLUME AIR FLOW A CIRCUIT HIGH
| Description: | The mass air flow (MAF) sensor circuit is monitored by the powertrain control module (PCM) for high air flow (or voltage) input through the comprehensive component monitor (CCM). If during key on, engine off (KOEO), or key on, engine running (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 hard fault. | |||
| Application | Key On Engine Off | Key On Engine Running | Continuous Memory | |
| All | refer to PINPOINT TEST J . | |||
