need help: vsc, trac off, check engine light ON

hi... My vsc, trac off and check engine light came on again... The mods I did was drop, rims and injen sr intake... I cleaned the maf sensor with electronic cleaner... That did not help...sometimes I smell gasoline by the gas cap... I take out the cap and put it back in... That did not help... then i did the obdII scanner...and got 3 codes...

1. P0441 evaporative emission control system incorrect purge flow

2. P0442 evaporative emission control system leak detected (small leak)

3. P0446 evaporative emission control system vent control circuit malfunction

Not sure what's that... But if anyone know please help... Thanks

The last time I had those codes with a Toyota, it was my fault.. I filled the fuel tank, and then topped off a couple times.. Then I parked the vehicle in the hot sun for a couple days after only driving a couple miles.

What happened was the fuel expanded into the charcoal canister and filled it.. Auto Zone checked the codes and reset it for me, and lucky for me, the guy who checked it had seen it before and told me to quit trying to pump gas in after the nozzle clicks.. :whatthe:

That was 2 years ago and I've never had a problem, since. :clap: I also quit trying to force more gas in the tank..:rolleyes:

My guess is, you're still under warranty?? Why not let the dealer take a look?

Just so you know, the trac off and VSC light are sensors that are tied into the CEL light sensor, they generally go off when the CEL light goes off.

I've been struggling with this same issue. In fact, my 02 Sequoia stalled three times today. I found this site - http://www.findarticles.com/p/articles/mi_qa3828/is_200207/ai_n9092642 (http://www.findarticles.com/p/articles/mi_qa3828/is_200207/ai_n9092642) - added brake fluid to the master cylinder and problem is gone... Go figure!!!

did u get this engine code after u fuel up the tank? if it is, try lock up the gas cap (with min. 3clicks after u tight the cap) and reset the code and it should be fine..... basically this engine code is emission issue....i know for the 98 to 2002 corolla and camry v6 they have a solenoid called VSV or tank VSV near the charcoal cansister always malfunction....try it first see if the gas cap tight first, otherwise u have to send your car back to the dealer to check if the vsv solenoid is okie or not....

ybike2: for your truck is different....since u have low brake fluid, which cause less fluid pressure to control your truck VSC system also your truck have EBD electronic brake thing...that's why it cause it stall....and cel light on.....one more thing, u truck have a special way to bleed the brake.....in which u have to go back to the dealer to do it....becoz of the VSC system....if u don't bring it back to dealer to do it, u might get the cel light again!

Filling the fuel past the click is a big NO NO on the xB. Hopfully they will fix it under warranty. It is an expensive fix if not. Good Luck Bro!

What up Jethro?!?!?!

funny find you every where...lol

Didn't tighten up my gas tank cap all the way and my did the same thing. Reset at the dealer and its good.

Your under warranty.
Go to the dealer instead of trying to fix it yourself.

I just had the same symptom, but it is the symptom of many different problems it seems. They had to replace several parts related to my timing to fix it up. I had to take it in 3 times before it was completely fixed.

I had the same problem when I installed my intake, I disconnected my battery for about 15 and let everything reset.

After using the car for over 50K miles and this problem starting to appear. I'll try these easy solutions see if it works. Thanks guys.

Else dealer for me. :(
