Product Details

The Standard Ignition V405 PCV valve regulates crankcase vapors as part of the vehicle’s emission control system.

The V405 is a direct-fit style service part for Nissan Sentra owners searching for a PCV valve replacement, crankcase ventilation valve, or emission control valve by part number V405.

Common Issues This Part May Address

• Excessive crankcase pressure from a restricted PCV valve
• Oil vapor buildup in the crankcase ventilation system
• Rough idle related to a sticking or clogged valve
• Oil leaks caused by poor crankcase ventilation flow
• Check engine concerns tied to PCV system performance

Installation Notes and Tips

Verify the thread size, hose size, and nipple orientation before installation. This valve installs with a screw-in connection and does not include a gasket, O-ring, cap, or hose connector, so reuse or source any required sealing components separately if your application calls for them. Confirm the vehicle is a 2003-2006 Nissan Sentra before ordering, and compare the removed part to Standard Ignition V405 for match-up.
