Detection Condition

PCM monitors Short Term Fuel Trim (SHRTFT) and Long Term Fuel Trim (LONGFT) values when monitoring conditions are met or DRIVE MODE 1 is run. If fuel trim exceeds preprogrammed criteria, PCM determines that the fuel system is too lean. This is a Continuous Monitor (CM). MIL illuminates if PCM detects malfunction condition in 2 consecutive drive cycles. Pending code is available if PCM detects malfunction conditions during first drive cycle. Freeze Frame Data is available and DTC is stored in PCM memory.
