ok so i got a CEL light last night on the highway bout 60 mph just cruising...

read the codes and they are

P0440
P0441b
P0446b

something about a purge valve????

cleared codes and so far they havent come back yet but if they do what next? like what do i need to start doing/looking for?

 

Sorry to hear you are getting other problems Brain.

Brain did you look in the codes thread in the DIY sticky: https://www.clublexus.com/forums/gs-...cel-codes.html

There are some ideas you can look at in the "Trouble Area" that may help.

Hope they stay gone.

nahh nigel i didnt, but i will now...i posted right before i left work...

u know u always call me brain instead of brian....going on vacation again tomorrow guys cya in a few days!

 

typeo typeo brain...brian.

Have a great time.

 

Clear the CEL. Change new gas cap. If CEL comes on again, you have a purging problem or a defective canister.

 

i have the same 446 code and i replaced my cap and reset the ecu..code came back..so im thinkin its the purge valve as ive heard that its common that it gets stuck opened or closed..the canister, i heard rarely goes out..is there a DIY on changing the purge valve?

 

hehehe its cool, i tease
i always try to...ne members on here from little rock wanna meet up tonight or tomorrow? yeah im starting to take your advice on my parts nigel... i have like 6 boxes scheduled to hit my work next week or so

i said i did clear the CEL'S since then they havent come back on, but since i have owned car i have had 2 unexplained ones....they came on, when i was driving to my mechanics work...they were still on, go inside get him and scanner come out, crank car and they GONE...NO HISTORY NO NOTHING! So this time i left the car on....

but like i said since he cleared them, i havent seen them again yet!

i dunno....im hoping i dont have to make it there ...im gonna wait and see if i get CEL code again and then i'll go from there

 

did you check all the tubes going in and out of the evap control valve?

 

nope...cleared the codes and was waiting for it to happen again...just got back from driving to little rock and all....STILL hasn't reappeared. so im gonna wait on it to reappear

 

lookin to try and tackle fog problem this weekend. will check my fuses first, but then what? bulbs are new...how can/do i check the ballasts? n then what if its not those..

edit fog problem solved....was a fuse

 

ok so guess what guys....sat night i popped ANOTHER CEL this time...

p440 again
p441 (not b this time)
p446 (not b this time)

so im gonna start doing some research i guess. i know im gonna look for a cracked hose on the purge valve....maybe a broken one, possibly a bad purge solenoid....what else do i need to know/look for?

 

ok problem resolved....for CEL codes P0440 P0441b P0446b

thanks....this was it! took it to my mechanic and he found out i had a dry rotted hose....replaced everything i needed for $30 and a week l8r no CEL lights

 

Those are the worst types of hoes.

 

i dont know any good ones though!

 

I'm having the same symptoms and pull the same codes intermittently like you were.

Can you tell me where the Evap Control Valve is under the hood ?
