Hi I also have this code I sometime smell gas in the back seat and under the car near charcoal canister will I need to replace my charcoal canister if so how will I go about takin off the canister pls help thanks

 

If you got a gas smell, check your vent to see if it's plugged. Its the hose with the biggest diameter and unplugged.

 

Thanks gs4 fiend for the reply n where will I go about findin the vent and the hose is that near the charcoal canister ?

 

it's above the differential. you will see a large hose sticking out with a hole.

 

n also i forgot to mention wen opening the gas cap i dont hear no pressure at all i replaced the cap n still no pressure

 

Reason why you got no pressure because you got a leak somewhere. The charcoal canister is above the differential. In order to see it, you would need to lift the car up high. The differential is the one that has 2 axles connected to. There's a picture above if you scroll up.

Now do you smell gas from the back seat all the times or just when you are filling up gas?

 

I only smell it wen the car is park mainly near my rims can it be the gas tank that's leakin ? I don't see no signs of stains or leaks on tank I'm guessing one of the hose n thanks for the info I will take a look at the stuff u suggested this weekend n also I'm getting 2 codes p0440 and p0446

 

P0440 - EVAP Control System Malfunction

Vapor pressure sensor and VSV for the vapor pressure sensor is used to detect abnormalities in the EVAP system. That sensor and VSV should be checked out. If you got no idea what you are doing, I suggest you take it to a mechanic.

 

P0446 Is a VSV code... There are a few other codes that point to certain things on the EVAP system and p0446 is def. the Canister purge Solenoid aka "Vacuum switch Valve" Itself .... I just Knocked this out earlier today an so far so good. the valve can be ordered thru your local auto parts store.. I got mine from Advanced auto and it turned out to be the ORIGINAL Toyota Part... $50 + tax
