Detection Condition

WARNING: This page is about a different car, the 2003 Mazda 6. However, it is still accessible from the selected car via links, so may be relevant.

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 more than 4.9 volts, PCM determines that 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.
