So. Every every so often i might get the code P0448, And a couple of days in the past the gas filler would spit out gasoline on the flooring. I believed it was once because of the frame raise i simply installed, But it was once not, It was once the vent control valve.Intended to be used in immunohistochemistry, immunoblotting and ELISA. The cross-reaction with human, mouse and rat immunoglobulins, and fetal calf serum proteins is negligible.

Possible causesFaulty canister vent keep an eye on valve Purge Control Valve harness is open or shorted Purge Control Valve electrical circuit deficient connection Tech notesVery not unusual drawback with Nissan automobiles. Before changing any portions, check for harm to the EVAP canister and for loose hoses from the vent keep an eye on valve to the canister.

When is the code detected?EVAP canister vent keep an eye on valve remains closed under specified riding conditions.

Symptoms- Engine Light ON (or Service Engine Soon Warning Light - this is what came about to me)

P0448 NISSAN DescriptionThe Evaporative Emission System (EVAP) canister vent keep an eye on valve is situated on the EVAP canister and is used to seal the canister vent. This solenoid (the EVAP canister vent keep an eye on valve) responds to alerts from the Engine Control Module (ECM). When the ECM sends an ON signal, the coil in the solenoid valve is energized.A plunger will then move to seal the canister vent. The ability to seal the vent is essential for the on board analysis of different evaporative emission regulate gadget partsThis solenoid valve is used only for prognosis, and generally stays opened. When the vent is closed, beneath customary purge stipulations, the evaporative emission regulate gadget is depressurized and lets in EVAP Control System (Small Leak) prognosis.

I've read on this and other boards that this will happen after off-roading or in case you spend numerous time on gravel roads. Thought I'd assist y'all out by means of posting an image step-by-step for how you can get to the vent keep an eye on valve and what to scrub out.

There are factory provider bulletins for this. I used this for help (for 2007 Xterra, however labored for my 2009): http://vpnavy.org/nissan/graphics/xterra_2007_dtc0448.pdf

Here's what I did to mend it:

Break lugnuts on rear, driver-side passenger tire. Jack rear of auto then transfer weight to jack stand for the remainder of the paintings:

Remove tire. Remove rear splash guard (trim panel fasteners and Philips-head screws):

This will have to disclose the EVAP canister simply:

The vent regulate valve is the furthest attached item to the canister. It's observed underneath, sitting at a Forty five stage angle to the precise. There is a wiring harness and tube connected to the vent control valve.

Remove the tube from the vent regulate valve and from the connecting part, nearer to the spare tire, completely. Mine had somewhat just a little of dust/mud pop out. Nissan's bulletin says to scrub with compressed air handiest. So that's what I did. No solvents.

I needed to jerry-rig this beneath to be able to take the wiring harness off. Can't imagine how exhausting it was once to get off!

Once the tube and wiring harness are off, there's a small tab you press down on, observed within the photograph under, which lets you turn the vent control valve CCW after which off. I found it to be more like 50-60 CCW turn, as a substitute of a 90 degree flip like others have mentioned.

I wiped clean the vent keep watch over valve out with compressed air as well, and verified I may just see sunlight between the 2 ends. The bulletin also says to glue the electrodes on the vent keep watch over valve at once to the battery to ensure function. See pic under. You will feel and listen to a click on, which is the valve ultimate.

Reassemble, transparent code, and also you will have to be excellent... till extra grime acculumates :iconbiggrin:
