Abstract
A positive crankcase ventilation (PCV) system for an engine includes: a PCV tube defining a flowpath extending along an axis; a damage detection circuit associated with the PCV tube. The PCV system also includes a damage detection module that selectively indicates that a fault is present in the PCV tube based on a change in a characteristic of the damage detection circuit and that illuminates a malfunction indicator lamp (MIL) when the fault is present.
