The PCV valve is mounted on the engine’s valve cover and connected to the intake manifold by a vacuum hose. On the 2010 Accord, the exact spot differs by engine: the 2.4-liter four-cylinder has the valve on the passenger-side valve cover with a short hose to the intake, while the 3.5-liter V6 places the valve toward the rear of the valve cover on the right bank with a hose to the intake plenum.
Engine variants and PCV locations
The 2010 Accord offered two engines, and the PCV valve location follows the same principle in both: it sits in or on the valve cover and is in-line with a hose leading to the intake. Use this guide to identify the precise position on your car.
- 2.4L inline-four (common in many trims): PCV valve on the passenger-side valve cover, typically near the back, with a hose running toward the throttle body.
- 3.5L V6: PCV valve on the rear portion of the valve cover on the right bank, with a hose leading to the intake plenum.
In both cases, you’re looking for a small black plastic (or metal) valve mounted in or near the valve cover with a vacuum hose connected to the intake. If you can’t locate it, consult a service manual or a Parts Diagram for your exact VIN to confirm the placement.
Quick identification tips
Stand at the front of the car with the hood up and trace the hose path from the valve cover toward the intake manifold. The PCV valve will be the inline component where that hose connects; it’s usually compact and may require a quick inspection for clogs or a loose connection.
Summary: On a 2010 Honda Accord, the PCV valve is mounted on the valve cover and connected to the intake manifold. For the 2.4L engine, look on the passenger-side valve cover with a hose toward the throttle body; for the 3.5L V6, check the rear of the valve cover on the right bank with a hose to the intake plenum. If in doubt, verify with your VIN-specific service diagram.
