Abstract
Method and apparatus for determining a probability of below-specified performance of a low temperature limit control valve. During operation of an environmental control system (ECS) for a vehicle, current operation parameters related to the ECS are sensed. Historical operation parameters related to the ECS are retrieved. A probability of below-specified performance of the low temperature limit control valve is determined based on a predetermined relationship between the stored current operation parameters, the historical operation parameters, and the probability of below-specified performance of the low temperature limit valve.
