Warm-Up Cycle

In addition, the execution of a DTC may also be bound by conditions which must comprehend a Warm-up cycle. A Warm-up cycle consists of engine start-up and vehicle operation such that the coolant temperature has risen greater than a certain value (typically 40°F) from start-up temperature and reached a minimum temperature of 160°F. If this condition is not met during the ignition cycle, the DTC may not run.
