DTC 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 ignition on engine off, the air flow voltage signal is greater than 0.27 volt the test fails. Likewise, if, during ignition on engine running, the air flow voltage signal is not within 0.46 volt to 2.44 volts, the test fails. | ||
| Possible Causes: |
|
||
| Diagnostic Aids: | A MAF PID reading greater than 0.27 volt (KOEO) or a MAF 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 |
