摘要： Methods and systems are provided for using a crankcase vent tube pressure or flow sensor for diagnosing a location and nature of crankcase system integrity breach. The same sensor can also be used for diagnosing air filter plugging and PCV valve degradation. Use of an existing sensor to diagnose multiple engine components provides cost reduction and sensor compaction benefits.

摘要： Methods and systems are provided for diagnosing each of a plurality of engine cooling system components including various valves and grill shutters. Each valve may be individually closed and opened for a specified duration, and corresponding changes in coolant temperature may be monitored. If all the components are functional, the various valves may be adjusted to stagnate coolant at the engine and expedite engine warm-up during a cold-start.
摘要翻译： 提供了用于诊断多个发动机冷却系统部件中的每一个的方法和系统，包括各种阀门和烤架百叶窗。 每个阀可以单独关闭并打开指定的持续时间，并且可以监视冷却剂温度的相应变化。 如果所有组件都是功能性的，则可以调节各种阀门以使发动机处的冷却剂停滞，并在冷启动期间加速发动机预热。
