On a 2002 Isuzu Axiom, the PCV (Positive Crankcase Ventilation) valve is typically located on the valve cover. It may be found near the rear of the engine, attached to a hose that connects to the intake manifold. To access it, you might need to remove some components for better visibility, but it’s generally a straightforward process. Always consult the vehicle's service manual for specific details.
