I pulled the code 1008 form my '95 GXE today, and this is the code for the Evaporative Emission (EVAP) Canister Purge Volume Control Solenoid Valve. If someone could post a pic of what the **** this thing is, that would be great. Also, is this a common problem with our 4th gens? If so, what goes on it? Thanks in advance guys--

1008
The Evaporative Emission (EVAP) Canister Purge Volume Control Solenoid Valve uses an on/off duty cycle to control the flow of fuel vapor from the EVAP canister. Diagnostic Trouble Code 1008 is set when the Engine Control Module (the computer) detects an improper signal through the valve. The problem is likely to be in the electrical wiring, harness, or the valve itself.

Check fuse #58 (10 amps) and replace if necessary.

The CPVCSV is easy to see and reach. It is located in the engine compartment, mounted to the top of the upper intake manifold. Notice the Vehicle Serial number stamped into the firewall. Put your finger on the third-from-last number. Move your finger three inches toward the radiator. That's the CPVCSV. It has one two-wire electrical connector and two vacuum hoses. It is directly above the ignition coil connector for cylinder #5 and has to be removed in order to replace the #5 coil or spark plug.

You may test the valve. This test procedure is performed with the engine off. Remove the electrical connector and both vacuum hoses. Fasten a length of clean rubber vacuum tubing to either nipple. Gently blow through the hose. The valve should be closed and it should be difficult or impossible to send air through the valve. Now use a pair of fused test leads to provide 12 volts to the electric terminals. The polarity doesn't matter. With the solenoid energized the valve should be open and it should be easy to send air through the valve.

I already read that, but the diagram was good. Is it easy to replace? Also, will it improve my gas mileage?

You might wanna check for charcoal in ur vaccum hoses and the purge valve. Reason is I have replaced mine 3 times along with the charcoal canister, purge valve, and solenoid and boost sensor. It is common only if u squeeze in the extra cents of gas like most people, cause some engineer thought it would be nice to put the overflow hose right into the charcoal canister and if u do this often it weakens the filter in the canister and the vaccum sucks all the charcoal through your engine and its a mess to clean out. Someone finally told me after the third time it happened. Hope this helps

I did this already on my 97, its an easy install if you have a lift. Its a couple screws. Gas Milages improves.

Good luck

I do in fact use 87 octane gas. Should I get the new valve and put it in? Also, do i really need a lift to put it in?

I replaced my evap contol valve (it was easy to do) about 3 years ago. It didn't make the code go away however. It's 65,000 miles later and my engine still reads a 1008 code! I wonder if it has anything to do with my CAI?

Anyone know where I can buy this part, and again, is it easy to put in w/out a lift?

I didn't need a lift, but I have a 1999 SE limited...and the part is located by the fuel tank instead of in the engine bay. You can buy this part at www.nissandiscountparts.com. They sell OEM parts for roughly half of the cost of going to the dealership or Auto Zone. They quoted me an OEM O2 sensor for $59 vs Napa at $99. You'll have to give them your VIN# when you place your order.

Why the heck would you need a lift to get to the top of the Intake manifold!?!?

exactly what i was wondering.

anyone have a part number for this?

If it's what I think it is (see diagram - highlighted in green) then the part number is 14930-40U01. (Ignore the part number in the diagram - that's not the real part number)



Can someone verify that this is what that is?

Thanks!
