Abstract:
Methods and systems are provided for detecting degradation of a crankcase ventilation tube. Humidity sensed from a humidity sensor in the crankcase ventilation tube may provide an indication of crankcase ventilation tube disconnection during different engine operating conditions. The humidity sensor may further provide diagnosis of humidity sensor function and engine degradation.
