PCV Valve & Vacuum Line

This automotive "how-to" guide was specifically written to assist owners of the 2009 Honda Accord LX Premium Sedan with the 2.4 Liter four cylinder engine in replacing the PCV valve.

Owners of other eighth generation Honda Accord coupe or sedan vehicles from 2008, 2009, and 2010 should also find this guide to be useful.

Other Honda vehicles such as the Civic, Element, Insight, Pilot, Fit, CR-V, Ridgeline, and Odyssey may have similar PCV (positive crankcase ventilation) valve replacement procedures.

To complete this procedure, you'll need a new PCV valve such as the Purolator PV1093 for the 2.4L engine, or the PV1070 for the 3.5L V6.

The only tools needed are a pair of needle nose pliers and a 17mm deep socket with ratcheting wrench.

Pull Back Hose Clamp
The first step is to locate the PCV valve and vacuum line going into the intake manifold located just above the alternator and below the water pump. Look for the red arrows in the first three pictures on this page.

Then use a pair of needle nose pliers to pinch and slide back the metal hose clamp that secures the vacuum line to the PCV valve's metal nipple. Once the hose clamp is out of the way, pull on the vacuum hose to remove it from the PCV. Wiggling the hose helps if you have trouble removing it.

PCV Valve Removed
With the vacuum line removed, place the deep 17mm socket and ratcheting wrench on the end of the PCV valve and turn it counter clockwise to loosen it. Once you have it spinning, turn it by hand counter clockwise until it can be removed from the intake manifold.

Installing New PCV Valve
If the old PCV valve still rattles, it's possible that it does not need to be replaced. You can also choose to clean the old PCV valve with brake cleaner. A new PCV valve, such as the Purolator PV1093 for the 2.4L engine, only costs a few dollars so you might as well replace it while you have the old one out.

Re-Attach Vacuum Line
Re-install the old PCV valve or a new one by turning it clockwise into the intake manifold by hand until it stops. Then tighten it about a 1/4 to 1/2 turn more with a 17mm deep socket and ratcheting wrench. Push the vacuum hose back onto the PCV valve's nipple and replace the metal hose clamp by pinching its tabs together with the needle nose pliers. Start up the engine and make sure it runs properly before taking it for a test drive.
