My SES light came on. I had Autozone pull the codes:
P0455 EVAP Control Gross Leak
P1448 EVAP Canister Vent Control Valve Open.

Anyone have any suggestions? I always tighten my gas cap until I hear it click.

 

Funny you should ask, the same codes came on in my 02 last week. Went to the dealer today, and with parts and labor its around a $600 repair. I'm gonna try to save some money by buying the parts from Dave. B. Good luck...

 

Same **** happened to mine a few months ago. Paid $450 to get it fixed because.....duh...of course it's not covered by the pos warranty I got. The parts alone are pretty expensive so I just bent over and took one for my max.

 

I have P1448 and P0447.....I always tighten my cap till it clicks as well. Sometimes when I fill up the light goes away completely but it comes back on before 1/2 tank.

Driveability seems to be fine...would it hurt the car to drive around like this for a few miles? Also, what exactly is the parts list for this repair?

What repairs did the dealer make?

 

New vent control valve + new evap canister + $150 labor Parts cost $275 alone and I was having trouble finding them. Today I'm putting on new rotors and pads so my max should be trouble free(crosses fingers).

 

ive had the same codes for about four months. a mechanic told me it wouldnt cause any problems and so far it hasnt. the dealer said eventually it will mess up my cat converter. im not sure who is telling the truth.

 

it will NOT eventually mess the cat converter up. svc advisors say that ish to get you in the shop.

youll probably end up finding a failed vent valve. should be easy to replace.

 

I'm just going to drive with my CE light on for awhile longer. I wonder if you can clear these codes with any run of the mill code scanner?

 

yes, an OBDII generic code reader should be able to clear them. or you can clear them per the procedure in teh how-tos

 

Hey guys going use this thread, I have 1999 nissan maxima 4th gen but I am sure its similar to 5th gen. So anyways, I went to shop for inspection and emission but emission failed due p1448 and p0440. And read FSM and said I should do p1448 first before anything.
Before I take canister out, do I need take fuse out of fuel pump to relieve the pressure?

Gas cap is passed.

Also the guy said If i need to replace the vent solenoid, I have to buy the whole canister. Is that true?

 

i have no idea i know i had similar codes once, once of the wires in the engine bay got pinched off or corrode some how or another.

 

You probably have a bad EVAP Canister Vent Control Valve. It is rather common with the age of the car because of its location.

And NO, you do not have to buy the EVAP canister. They are sold separately, so you only buy what you want or need.
