Detection Condition

DTC is set if difference between maximum and minimum input value of ECT is less than 10.1°F (5.6°C). Difference is measured after allowing vehicle to be off for at least 6 hours and starting vehicle and allowing it to idle for 5 minutes. This is a Continuous Monitor (CM). MIL illuminates if PCM detects malfunction condition in 2 consecutive drive cycle. Pending code is available if PCM detects malfunction condition during first drive cycle. Freeze Frame Data is available and DTC will store in PCM memory.
