Genuine 12204-62030 PCV Valve Sub-Assembly Ventilation Valve

The Genuine 12204-62030 Valve Sub-Assembly is an OEM positive crankcase ventilation (PCV) valve designed for select Toyota and Lexus vehicles. This critical emission control component regulates the flow of crankcase vapors from the engine back into the intake manifold, reducing hydrocarbon emissions while maintaining optimal engine performance.

Key Features:

• Genuine Toyota OEM part ensures precise fit and reliable operation
• Restricts flow during high vacuum conditions to maintain proper idle quality
• Prevents excessive blow-by gases from causing engine seal leaks
• Helps reduce emissions and maintain fuel efficiency
• Manufactured to Toyota's strict quality and durability standards

A malfunctioning PCV valve can cause symptoms such as rough or erratic idle, excessive tailpipe smoke, oil leaks, or a hissing sound from the oil cap while the engine is running. Regular inspection and replacement of the PCV valve during routine maintenance helps ensure optimal engine performance and emissions control.
