Detection Condition

PCM monitors Mass Airflow/Intake Air Temperature (MAF/IAT) sensor signal at PCM 104-pin harness connector terminal No. 39. If PCM detects MAF/IAT sensor voltage of 4.84 volts or more, PCM determines MAF/IAT sensor circuit has a malfunction. This is a Continuous Monitor (CM). MIL illuminates if PCM detects malfunction condition during first drive cycle. PENDING CODE is available if PCM detects malfunction condition. FREEZE FRAME DATA is available. DTC is stored in PCM memory.
