P1448 and P0455: EVAP air leaks - Maxima Forums"Here\'s your answer:

The EVAP codes you are getting are directly related to your

\'vent control valve\'. This is VERY COMMON on this generation

Maxima. Up under yer car behind the left rear wheel is your

EVAP canister. (black plastic box) Your vent control valveis

bolted directly to this canister, with 2 screws. There should

be a vacuum line connected to it. Be sure it IS, and that it

looks like it\'s in good condition.

These valves are notorious for going bad, even more

so than the ignition coilpacks! They dont cause any

decrease in performance, but it usually decreases gas mileage,

and it will cause it to fail emissions testing. But worst of all, it

makes that MIL light on the dash flash...

It\'ll cost ya about $60 from the dealer.. have yer VIN ready..

there are 2 different ones for this generation: 1 with a nipple

and o-ring, the other with no nipple (requires separate o-ring).

Part #\'s: 14935-54u04 OR 14935-54u06

That code is an emissions cannister leak and is not related to the engine failure. IT is most likely the crank shaft sensor that is bad.

I fail to see why you tried to ruin the motor
& may have succeeded

Drive 60 miles AFTER it overheats
Then drive 3 weeks without wondering about
the overheating issue

Someone should take the car away from you

Stupid & then tell the whole world on the internet

Hey Shawn,here's a guide to check.

P1448 NISSAN - EVAP Canister Vent Control Valve Open

Possible causes- EVAP control system pressure sensor and the circuit
- Blocked rubber tube to EVAP canister vent control valve
- EVAP canister vent control valve
- Water separator
- EVAP canister is saturated with waterWhen is the code detected?EVAP canister vent control valve remains open under specified driving conditions.

unfortunately in your mode maxima nissan had quite a few issues because of beeing the first model of A32 body style from the older J30 model maxima. from what i have seen in the past it could be anything from bad harness, to flodded ECM/computer because of water entering into vehicle because of faulty cowling on top of windshield, to bad ground between trans and engine housing. if the check engine light is on, you need to scan for codes to get started. if no check engine light is on that that makes it alot harder to diagniose. if no check engine light is on, i would look at the top of the computer bracket to see if its rusted up, that coilud be sign of water coming in and flodding computer causing running issues/drivability porblems.

code p0306-misfire detected in cylinder #5 code p1448-vlt suppy output too low.

Both Codes show an Emission Controls problem - very likely a large leak. Give it a really good visual and look/listen for a vacuum leak or hose off in the emmission system.

try locking and unlocking the doors with the keys that is what i did and it solved my porblem
