DTC P1101 MAF sensor out of self-test range
DETECTION

voltage) input. If, during KOEO, the air flow voltage signal is more than 0.27 V with
the ignition switch in the ON position (Engine off). Likewise, the test fails if the
airflow voltage signal is not within 0.46 to 2.44 V with the ignition switch in the ON
position (Engine running) (KOER).
