Re: 1997 nissan pick up
Your charcoal canister is there to soak up petrol fumes etc so they cant escape to atmosphere and to help eliminate risk of vapours creating a fire hazard.They are a good thing for the enviroment Im suprised its falling out.Its usualy well protected.

This code means that you have a problem with purge flow. This is a relatively difficult problem to diagnose and you should know that this type of problem can be challenging even for professionals with proper diagnostic tools.
You know how a container of liquid can inflate itself if left in the sun? (like one of those plastic gas cans)
Well the gas tank on your car would do the same thing if it wasn't vented. But the good ol' EPA doesn't want you venting gasoline fumes into the atmosphere so the vented fumes are filtered through a charcoal canister first. The gasoline molecules are trapped in the charcoal canister. While you are driving the vehicle at cruising speed, the purge valve is opened (by the car's computer) and allows your engine to suck in the fumes from the charcoal canister and burn them. That last bit is Purge Flow.
Check your vacuum hoses and the hoses coming from the charcoal canister to the purge valve and from the purge valve to the intake. If it all looks solid, I'd suspect your purge valve is either stuck or broken mechanically. If it is stuck you might free it up by taking it off and cleaning it. There is a way to test it but involves electrical knowledge and skill and you may have to put your mouth on it. (I'm talking about blowing air into it wile jumping power and ground to it in a very small connector).
Check that your intake is not clogged with carbon buildup where the purge valve connects. Some intakes have very small passages for purge flow that become clogged easily.
In rare cases the charcoal canister gets clogged.
My advice to novices is if you don't see anything obviously clogged or leaking, then just replace the purge valve. If that doesn't do it, take it to a good mechanic with ASE Certified Technicians.
The IAT sensor is located in the air filter case on top of the throttle body. If you remove the air filter you can see it on the left side of the case on the bottom. It connects from underneath and the connector can easily be damaged if you are not careful when removing the lower part of the air filter housing from the throttle body. If you replaced the MAP sensor you may have damaged the connector or pulled a wire loose.
If your evap canister has ruptured then your evap lines will be full of carbon pellets. You will need to disconnect each end (evap canister line towards front) and evap canister purge line towards the rear and blow out these lines with compressed air. Once they are clear replace the evap canister and check the vacuum canister cut/bypass valve as described in the link. If you fix this your self you will save close to $1000 as opposed to what a dealer would charge to fix this problem.
P1447 purge volume control solenoid valve Usually charcoal canister has ruptured and vehicle needs canister. entire system will have charcoal pellets in it. pull the hose at solenoid and see. solenoid can sometimes be cleaned by tapping and blowing with your mouth not compressed air. sometimes needs to be replaced. remove canister and remove pressure sensor(by canister and blow out charcoal with compressed air. wear safety glasses. you will need to blow from both ends several times. don't give up at first nothing comes out and when you pull air gun away charcoal comes out on your hands from pressure release
Codes with the 1st digit starting with a '1', is specific to that manufacturer.
Code P1442: Evaporative Emission Control System Leak Detected
This indicates a fuel vapor leak in the EVAP control system. In fact, the leak can be from a hole as small as 0.04" in diameter. The (EVAP) emission control system prevents the escape of fuel vapors from a vehicle's fuel system. Fuel vapors are routed by hoses to a charcoal canister for storage. Later, when the engine is running a purge control valve opens allowing intake vacuum to siphon the fuel vapors into the engine.
A loose or improperly affixed gas cap
A non-conforming gas cap (i.e. not factory/original brand)
Hi, all vapour cannisters are of the same design. Fumes are drawn through a charcoal medium "and cleaned"plus the fumes condensate is absorbed by the treated charcoal The major differences in designs cover the physical size of the cannister and the layout of the fittings. In theory it is possible to fit any cannister to any vehicle using modifications to the cannister body / shell.
maf sensors identify the amount of air flow flowing in the intake. the sensor works with the throttle so it knows how much air is coming in to add the proper amount of fuel to mix with the air. Easy to pull and replace.
to start with bleed your injectors even if you already have most important.if it is electronic inject you may have logged a fault otherwise where fuel line enters injector pump undo bolt and check small filter basket for blockage
