Detection Condition

PCM monitors input voltage from Mass Airflow/Intake Air Temperature (MAF/IAT) sensor when engine is running. If input voltage at PCM 30-pin harness connector terminal "1P" (Gray/Black wire) is less than 0.21 volt, PCM determines MAF/IAT 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.
