my 2002 4wd dc trd is throwing these codes

-p0440- bad gas cap or loose or evap stuff loose or not conected
-p0441- leak in evap system or faulty purge vsv or blocked vsv
-p0446- faulty ccv vent control solenoid

replaced gas cap from stealership gave it 2 days for the light to go off, still hasnt?


checked the general area of the evap system and checked connections and found no problems.

any ideas on what i can test or check? where is the ccv vent control

oh and the truck doesnt run any different from normal.

any imput is appriciated thank you

 

oh so even if i did fix it with the gas cap the light wont go off till i reset it?

 

correct, disconnect the neg battery cable for about 5 minutes and you should be good to go.

 

thanks

 

Not trying to hijack your thread, but I was wondering how everything turned out for you?

My truck is throwing the same 3 codes, I just ordered a Stant gas cap, which is supposed to be an OE replacement. I am hoping this will solve the problem, otherwise I'll be troubleshooting as you did.

 

i bought a new cap and took off my neg battery terminal for 10 sec and prob fixed. do you have a body lift?

 

No, no body lift. I'm getting the new cap in the mail tomorrow so hopefully that will solve my problems as well!

Your truck looks good by the way. What kind and how much of a lift do you have and how much did it cost you, if you don't mind me asking.

 

yea after you get the cap do the battery thing to reset the light, it should stay gone.

i have fabtechs kinda basic adjustable coil overs with light racing ucas and rear fabtech leafs with a inch and a half block. suspention is about 3 1/2 inches of lift and i have a one inch body lift. reason i ask about body lift is cause when i did mine it pulled on my gas spout, and pulled it in a bit and my cap couldnt get a good seal soi think thats why the light came on,so i fixed that but still bought a cap.

got my suspention setup for 500 bucks used and body lift for 140 and uca for 400

just waiting on rims and tires now!!

 

Who makes a decent BL kit? I'd like to put a 3" lift on my truck, don't think a suspension lift is in the budget right now.. plus I don't do a whole lot of off roading.

 

cant go wrong with toytec but i would stay away from the body lift if you can. try saving up and getting like a OME lift from them. for a little bit more money you can have almost a new suspension.

 

got it from wheelers off road. i love my one inch
