P1102 - MASS AIR FLOW SENSOR IN RANGE BUT LOWER THAN EXPECTED
| Description: | The mass air flow (MAF) sensor circuit is monitored by the powertrain control module (PCM) for low voltage input through the comprehensive component monitor (CCM). If during key on engine running (KOER) the voltage changes below a minimum calibrated limit, the DTC is set. | |||
| Possible Causes: |
|
|||
| Diagnostic Aids: | When EGRP is 0% to 50% between 700 RPM and 2400 RPM and the MAF/IAT sensor reading is less than a minimum threshold value, a concern is indicated. | |||
| Application | Key On Engine Off | Key On Engine Running | Continuous Memory | |
