What PCV components are inspected?

• A. PCV valve and PCV hose, with connections intact and no cracks.
• B. PCV computer module.
• C. PCV valve only.
• D. PCV hose only.

Answer: (A)

The PCV system is checked by looking at its two main components—the valve and the hose—and making sure all connections are secure with no cracks. The valve regulates crankcase ventilation using engine vacuum, and the hose carries blow-by gases from the crankcase to the intake. If either part is damaged, cracked, or disconnected, vacuum leaks or improper ventilation can occur, leading to issues like rough idle or increased emissions. So the visual inspection targets both the PCV valve and the PCV hose, with all connections intact and free of cracks to ensure the system functions properly.

The option that includes both components and specifies intact connections with no cracks is the best fit because it covers the actual parts that can fail in a typical PCV system. Checking only the valve or only the hose would miss potential problems in the other part, and a PCV computer module isn’t a standard component in a basic PCV system.
