Where is the PCV hose?

The Positive Crankcase Ventilation (PCV) hose is typically located in the engine bay, connecting the PCV valve to the intake manifold or air intake system. Its purpose is to allow the release of gases from the crankcase back into the engine for combustion. Depending on the vehicle model, the hose may be routed differently, so it's best to consult the vehicle's service manual for precise location details.
