The PCV valve on a 2013 Honda Accord is mounted on the valve cover and is connected to a hose that runs to the intake manifold; you’ll typically find it on the engine’s valve cover with the hose routing toward the intake/throttle area. Exact positioning can vary slightly by engine option, but it sits on the valve cover as part of the PCV system.
Locating the PCV valve on your 2013 Accord
Here is a quick walkthrough to locate and inspect the PCV valve on most 2013 Accord models. The PCV valve is a small, cylindrical part connected to a hose that runs to the intake manifold; it sits on the valve cover.
- With the hood raised, locate the engine’s valve cover (the large metal cover on top of the engine).
- Look for a small plastic or metal valve mounted into the valve cover with a hose attached to it; this is the PCV valve.
- Follow the hose from the valve toward the intake manifold or throttle body to confirm it’s the PCV line.
- Check that the hose and valve are not cracked, brittle, or clogged with oily residue.
If you can’t locate the PCV valve or the hose routing looks different on your trim, consult the owner’s manual or a dealership technician for the exact location and model-specific diagram.
Replacing or servicing the PCV valve
If you need to replace the PCV valve, follow these basic steps. Make sure the engine is cool, and keep track of any fasteners and hose clamps.
- Identify the correct PCV valve for your engine (2.4L I4 or 3.5L V6) and purchase a genuine or OEM-compatible valve.
- Relieve any vacuum by disconnecting the battery ground strap if needed, then detach the hose from the valve cover.
- Remove the old PCV valve by twisting or pulling (some models use a quarter-turn; others pull straight out).
- Clean the valve port, inspect the connecting hose for cracks, and install the new PCV valve, ensuring it seats firmly.
- Reconnect the hose, secure clamps, and start the engine to confirm it runs smoothly and that there are no vacuum leaks.
After replacement, check for oil leaks and any diagnostic trouble codes. If you notice rough idle, misfires, or a check-engine light, re-check the installation or have a technician inspect the system.
Maintenance notes
PCV valve function affects idle quality and emissions. Regular inspection and timely replacement help keep the engine running cleanly and efficiently.
Summary: On a 2013 Honda Accord, the PCV valve is mounted on the valve cover and connected to a hose that leads to the intake manifold. To locate it, open the hood, identify the valve cover, and look for the small valve with a hose attached; replace it if it’s clogged or damaged, using the proper valve for your engine variant.
