Detection Condition

PCM monitors Intake Air Temperature (IAT) sensor signal at PCM terminal "4N". If voltage at PCM terminal "4N" is less than 0.2 volt, PCM determines that IAT sensor circuit has malfunction. This is a Continuous Monitor (CM). MIL illuminates if PCM detects malfunction condition during first drive cycle. Pending code is not available. Freeze Frame Data is available and DTC is stored in PCM memory.
