Greetings,

Took the Maxima to the dealership (I now know to go to Autozone), due to SES light and got the following codes from them:

P0455 - EVAP Control System Gross Leak
P1455 - Purge Volume Control Valve

This doesn't tell me much about what the problem might be. They wanted to change the MAF and the Vent Control Valve. Of course, I told them to take a walk (they wanted $525/$116 for the parts and $400+ for labor), I could buy the parts from Dave B and then spin the wrench myself. I have ordered the parts, however, I'm not convinced that the MAF should be swapped, especially since it is not giving any of the usual codes which would be associated with the MAF.

I despise the dealership and felt like I was about to get it in the can, so I declined the service, at which they cried and basically told me I was a fool for driving away a car which could leave me stranded in traffic. I'd rather save the money and do it myself.

Does anyone have any experience with this pairing of codes? I have not been able to find anything about these two codes. What would cause an EVAP control system gross leak? Honestly, my first thought about this was that this was A/C related, but I know that this is not the case, but I'm not clear as to what system this is in, please be kind in explaining.

The second code has me at more of a loss, Purge Volume Control Valve. This code was not on the sticky, found it via Google, but there has not been any type of explanation that I could find. What is this?

Do appreciate the forum and any replies which may be contributed in advance.

"P1455 = EVAP canister purge volume control valve or circuit fault" is not a code for your car being that it is a 2002 model. Any code that comes up on a obd II scantool or consult machine that starts P1 is for the 4th Gen Maxima. The 5th Gen & 5.5 Gen only throw codes starting P0. So basicly this guy was trying to shaft you go else where like autozone & have them read the codes & print them out if possible & take them to Nissan & if your a big guy find the man who told you your car threw this code & knock out his teeth .

 

P.S the only code that comes close to being a P1455 on the 5.5 gen is a "P0447=Evap emission system vent control valve circuit"

 

You have no idea what your talking about.

I can go pull p1320 off my 5th gen right now.

 

P0455

Possible Causes:
Fuel filler cap remains open or fails to close.
Incorrect fuel tank vacuum relief valve
Incorrect fuel filler cap used
Foreign matter caught in fuel filler cap.
Leak is in line between intake manifold and EVAP canister
purge volume control solenoid valve.
Foreign matter caught in EVAP canister vent control valve.
EVAP canister or fuel tank leaks
EVAP purge line (pipe and rubber tube) leaks
EVAP purge line rubber tube bent.
Blocked or bent rubber tube to EVAP control system pressure
sensor
Loose or disconnected rubber tube
EVAP canister vent control valve and the circuit
EVAP canister purge volume control solenoid valve and the
circuit
Fuel tank temperature sensor
O-ring of EVAP canister vent control valve is missing or damaged.
EVAP control system pressure sensor
Refueling control valve
ORVR system leaks


P1455

There isn't a P1455 code for a 2002, according to the FSM. The closest to your description that I saw was P1444 EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE.

 

Hey Joel can you post all the P1xxx codes for the 5th gens?

 

No, because they are already in the Stickies.

all I can tell you is what is in my manual & no where is there a P1 code for a 5th gen unless maybe early production 2000 models threw them that I would not know. My manual only has p1 codes for 4th Gens only. And the above mentioned code you said above P1320 says it is a 4th Gen code for ignition signal primary circuit fault.

 

Not sure what manual you're using, but the FSMs for 2000 (early) and 2000 (late) both have about one page of codes starting with P1xx. They are on EC-14, for reference.

 

Ya I stand corrected I just checked my FSM & there are several P1 codes in there for 5th Gens Thats what I get for quoting a brand new Haynes manual that was sitting in my lap while checking the board. As far as punching that guy in the teeth go ahead & do it anyway he has probably charged a million people for rear wheel alignments.

 

Looks like I'll be heading down to Autozone today to see what codes that they pull off, as it seems to me that the codes that they gave were crap, let alone what they wanted to do to fix them.

I'm, of course, getting very hot over how this whole thing has been handled by the dealer, I'm sure that they've done this to countless others who would not question what is occuring and would have robbed them blind.

I'll let you know what they pull and how I handle the dealer as it progresses.....

I guess we were too caught up in the code issues last night to ask, but is the car showing any abnormal symptoms? How does it run?

 

Actually, it runs fine, has lots of power. I had the MAF changed at about 30,000 miles under warranty, which had me suspect of the latest recommendation.

I did have a case where it would die upon starting, but this only happened once and was a few weeks before the SES and it was abnormally cold.

I have not refilled the tank since the light came on, but I did crack the gas cap this morning (she's at half a tank) and it had pretty extreme whistling, so I'm venturing to guess that the vent control valve needs replacement.

I'll still go check out the codes at Autozone, as the 1445 is very suspect in my mind and I want to make sure that I've got all of the right codes in place before I go blow a gasket at the dealer.

 

Sounds like it has nothing to do with the MAF, IMO. A MAF failure doesn't always come with codes, but there are usually symptoms including low power, stalling and surging, inability to rev over 2400 rpms, etc. But yeah, get the codes pulled again and update em here.

 

Here's the codes that were pulled by Autozone.

P0113 - Intake Air Temperature Sensor Circuit High Input
P1448 - EVAP Canister Vent Control Valve Open
P0445 - EVAP Canister Purge Volume Control Solenoid Valve Circuit Shorted

Completely different than what the damn dealership indicated. I guess I'll start looking on how to resolve these codes. Any input would be appreciated

 

TAKE THAT RECIPT, GO BACK DOWN TO THE DEALERSHIP, TALK TO THE HEAD OF THE SERVICE DEPARTMENT, SHOW HIM THE SLIP, AND ASK HIM WHAT KINDA BUISNESS IS HE RUNNING!

 

Is the IAT not integrated into the MAF on an 02? That's why they wanted to replace the MAF. The other codes suggest what the dealer quoted you. What is the dealer going to do for you when you go back to freak out?
They diagnosed your concern. Although the labor quote seems steep.

 

It is "integrated" in a sense, but its only a thermistor. You can easily pull it out and replace it without replacing the MAF itself.

 

I had a code p0440 evaporation control system malfunction popup twice in november. After I noticed the symptoms of possible MAF Failure i.e. lost of power and surging in low RPM I called up DAVE B ordered a new MAF took it the dealer to install the MAF and reprogram the ECU. I asked them to check the cause of code p0440, after charging me 1hr diagnostic they could not find a problem and they told me it was probably the bad MAF.... So far so good.

 

Looks like I'm going to just replace the MAF (thanks to Dave B) and then replace the vent control valve, which hopefully take care of the problem. Granted the stealership gave me the wrong codes, but perhaps the right fix, still a little pissed about how was treated and the attempted raping on the labor as well as the parts, let alone their attitude.

 

Good to know that it'll be all worked out, I hope that solves everything. And yeah, Dave B is a great resource for us all.

Dealerships just keep perpetuating that reputation don't they?

 

I own a 2000 SE and got both of these codes (P0455 - EVAP Control System Gross Leak P1455 - Purge Volume Control Valve) three days after I bottomed out on about 5 inches of concrete... Guy almost hit me in a parking lot, so I was only doing like 5 mph, but it was either let him take out the entire front end or swerve and barely scrape a concrete stump... No driving issues, everything runs great, no noises or anything... By the way AUTOZONE told me that the P1455 would not read out on their scanner, only the dealer can tell you what that is... "Anything with a 1 as the first number of the code can not be read on our scanner"

 

Greetings,

saw the P1448 with my own eyes, so perhaps a different scanner was in use at our Autozone. Did finally replace the MAF and Vent Control Valve, about ten minute job for both parts, runs like a charm and no SES light (although it did take about 100 miles for this to go away).

 

Good to know that things worked out for ya and that blowing a ridiculously large amount at the dealership was avoided.
