P1103 - MASS AIR FLOW SENSOR IN RANGE BUT HIGHER THAN EXPECTED
| Description: | The powertrain control module (PCM) monitors mass air flow values. If, during a key on engine running (KOER) self-test, the MAF sensor values are greater than the calibrated values, the test fails and a DTC is stored in continuous memory. | |||
| Possible Causes: |
|
|||
| Diagnostic Aids: | When EGRP is 0% to 50% between 700 RPM and 2400 RPM and the MAF/IAT sensor reading is greater than a maximum threshold value, a concern is indicated. | |||
| Application | Key On Engine Off | Key On Engine Running | Continuous Memory | |
