Check the clips...sometimes they do corrode. check if there is voltage present when you turn on the defogger. if there is voltage, then the defogger itself is faulty. it could just be a loose connection at the clip.

watch out, the clip is very hard to pull.

if there is no voltage, then trace the circuit , it could be a bad relay or fuse.

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

Code 455

code 455 means large evap leak Check 2 possible places. On the passenger side, in the engine compartment, just behind the headlight, is an EVAP cannister with a few hoses on it.
Check each hose carefully, especially on the formed bends of the hoses for cracks.
Often one of the larger hoses will split at the formed bend in the hose, right where it connects to the cannister.

If those hose check out ok, then under the cab on the passenger side, on the frame, you will find another cannister. On the top of the cannister, a bit out of view, is a few other hoses. Often, those hose will split or come loose from the cannister, right at the connections.

With the EVAP large leak code, it is likely that one of the hoses has split or come loose from the connections.

When i put gas into my 2006 nissan sentra it comes out, i have to put a little in at a time, it takes for ever to fill it up. when i open the gas cap it has a lot of pressure built up.

This sounds like a problem in the evap system. The system consists of a charcoal cannister that traps gasoline vapors from the fuel tank, stores them so they aren't released into the atmosphere, and when certain conditions are met, a purge valve opens and purges the vapors from the cannister to be burned during combustion. Either the cannister is faulty, the purge valve solenoid is faulty, or you have a bad gas cap. If the check engine light is on, take the car to an autoparts store and have the computer scanned for fault codes. Most parts stores will do the scan for free. The codes should help identify what the problem is. Hope this helped and best wishes.

Service engine soon light came on.

Computer thinks the pressure is wrong in the EVAP cannister. Cannister could be plugged, vent hose could kinked, sensor messed up, or the vent solenoid is busted.

1. Loose/faulty gas cap.
2. Evap Canister problem - bad solenoid, leakage, etc.
3. Bad fuel tank pressure sensor.
