Hi all:

Does anyone have any sources for a new charcoal canister for my 95? I believe it has the Federal style, with the coffee can shaped canister in the engine bay. I have been able to find the other rectangular canister but not the kind I need. The dealer told me it is discontinued and I can't find one on Amazon or ebay and would prefer new rather than buying used and risking getting something worse than what I have now. I also can't find any non-OEM equivalents.
Basically, I'm getting a gas odor after driving the car and the dealer can't find any other sources for the gas smell. I may just have to live with it but thought I would reach out to the board.

 

i would think gas smell would be an injector issue. codes?

 

Yes. And a possible leaking fuel line. Bad canisters have been known to throw check engine codes.


I don't know if this canister is a match for your 1995 model. But the 1995 300zx used a round canister. The problem with the round canisters for the z-car is the cost starts at $180 (Rockauto). Unfortunately, I don't see the Intermotor CP450 (round canister) listed for the Maxima so its a gamble on compatibility.

Personally, I would try find a local parts store with a CP450 in stock and compare it to your old canister. That's the best I could do.

 

I found a thread with a picture of the round canister in the link below.

Here's a picture of the CP450 to see if the connections look like yours.

 

It has no ties to the ECU at all 0%. you could tear it all off and the car wouldn't even know it.

I have one that i could sell you it was taken off a 8 year old 95 max(but it was in the junk year 2-3 years of that). I was gonna convert my race max i had years ago. To that setup. but just deleted it altogether . It is a little dusty been sitting in a box for a long time. I can clean it up and take a pic if you would like

 

This picture does NOT match the 95 max canister. The 95 bottom doesn't look like that.

 

this would work great same hookups same spots brand new $63. The only thing is the diameter of the canister is a little smaller but thats easy to solve clamp is just a band.

I would inspect the basics like the fuel line going into the filter then into the fuel rail. Inspect fuel rail itself, connection points to injectors, etc... Replace the fuel lines coming into the fuel rail and out of it. They are cheap and easy to replace even if they look ok

 

Is that the same thing as the vapor canister?

Rock Auto has the California-spec canister about $55, a rectangular-shaped one, maybe it can b used on the federal versions?

I was able to find the part number for the federal-spec round canister. The part number is CP3243 for the Standard/Intermotor brand

Napa appears to have the federal-spec round canister for $239. The Napa part number is CRB 220136

 

Krismax... I may have located a canister. Have you replaced yours before? I'm trying to get an idea as to the difficulty of the job to see if I want to attempt this or pay to have it done. I checked the sticky's and there isn't a write-up on this job.

 

As has been stated previously, I'm certainly hoping that you going through all of these motions isn't all for naught.

Hate to see you do this and have it turn out to be an failing injector or an old gas cap.

 

^^ +1 - The cases of canister failure that I've experienced resulted in charcoal leaking into the evap system lines and the system throwing codes.

 

Thanks all. I really appreciate this input. A failing injector would result in a CEL right? What about a failing gas cap? The emissions place always tests the gas cap so last time I had the inspection it passed. Perhaps I should take the car there and see if they could just check the gas cap? Maybe this is the cause - I hadn't thought of that. II only smell the gas after the car is run, shut off, and parked. For what it's worth, the service manager at my dealership I go to sometimes says they have seen canisters fail on the 95's but you are right, replacing this to see if it solves the problem is like rolling the dice and they even said that too. This is why I was asking about the difficulty of installing it myself to at least save the install cost if it is the same afterwards. They claim they have checked everything already when I recently asked if I should pay for an additional inspection if I have them put it on (they did a pretty extensive visual inspection).

 

A key question to answer, for me anyway, is where do the fuel vapors appear to be coming from?

- the fuel filler area;
- from under the car ... if so, what general area?
- the engine compartment ... again, if so, what area?
- the exhaust tip;

A failing injector will not necessarily generate a DTC, nor will an old worn gas cap. If your asking about codes so as to possibly rule these items out, the answer is no ... can't rule them out.

 

Thanks Turbobink:
Great input. Here are some answers:
gas smell seems to originate from left side of car and not engine area. At first the Nissan mechanic said it would make sense to have a smell there as there is a vent that would activate with a failing charcoal canister but then he later said that vent runs along the gas filler neck and has a cap - so I'm a bit confused about that logic now. I've never opened the gas filler cap after shutting down the car and driving to see if the odor is coming from the gas cap but will do that. I also have an emission check station near me and I bet I could talk them into checking my gas cap if I smell anything. I'm confident there are no rusted lines anywhere as the car is in great condition with basically zero rust. Plus the mechanic had it up on the lift and gave it a thorough inspection. Plus I crawled underneath the car (left driver side rear) where smell originates from and all looks good hose and connection wise.

Regarding codes... question.. if the CEL is not on, does that mean there could still be codes that could be retrieved via a scanner? If so, this might be worth checking but I always thought it CEL was off, all was OK in that department.

 

Yes, there may be codes present even with the CEL off

 

Hi all:
I've never had to retrieve codes. Do auto parts store provide this service out in the parking lot or should I just buy a scanner from PepBoys or the like? If the latter, which kind do I look for? I checked the sticker on my car and production date is 4/1995 so not sure if that is OBD1 or OBD2. There is a connection under the dash on passenger side that I've seen the emissions place hook into sometimes. What about the Nissan Consult system? Does that retrieve identical information? Should I have that done too if not?

 

the connector on pass side is OBD2 , all 95+ maximas are OBD2

 

this

 

Thanks fellows.

So regarding the Nissan Consult tool they have at dealers, would that tell me anything different than a scanner I would buy? I can't say for sure if they checked my car with their Consult tool. Will any scanner work for me? I found one as cheap as $15 at PepBoys.

Also, at one point someone recommended checking the gas filler neck itself so I removed the four fasteners holding the plastic shield and all looks OK. There was a smaller diameter tube running parallel to the filler neck. What is this for? I thought perhaps it was an overflow drain to the ground but it isn't.

 

Not here in Aus haha, i know cause i have a 1995 Max, RHD AU Spec, and it ain't got OBD2, i've searched everywhere for it, and also searched again when i had the center console and radio out doing some Accessory wiring upgrades, the port simply doesn't exist on mine, Zip, Zero, Nada, 404 Port not Found.

For me, i use "ECUTalk" (Freeware) with a "USB Consult" (Cheap on ebay) adapter on my windows tablet, that allows me to read and clear codes, as well as watch detailed live data (updates very fast too!). ECUTalk can also log to a CSV file for you, very handy.
