question... my CEL is on and it gave a p0441-emmissions leak code... the guy at autozone said there's no leak in the vaccuum tubes so to spray TB cleaner around my gaskets to check for a leak there, will that be ok? will that work?

 

Hey I just got the 0442 code the other day (same basic thing I believe). My leak was from the gas cap (I think)..... Didn't screw the biatch on all the way (it was loose when I checked it).

 

I've filled up the tank since it came on and tightened my gas cap then disconnected the battery to reset it. It just came right back on.

 

that will work spray the tb cleaner around there if the engine revs up you have a leak

 

Well, damn! Nothing! It didn't rev. So, now what? Take it in to a dealer?

 

probably your best bet

 

you guys are shooting in the wrong direction

the guy at autozone mis informed you

the emissions system leak you have is in your EVAP system...

it means your gas tank is not staying pressurized within the limits the ECU wants, aka you are letting gas evaporate into the atmosphere...

i dont know how to trouble shoot this other then take it to an emissions testing station and having them compress your tank to verfiy it is a leak and not just a bad sensor *the purge valve sensor*

hope this helps.

p.s. here is what i found on the HMA site

http://www.hmaservice.com/webtech/iindex.a...1555#_394891555

Fuel filler cap loose or missing

Fuel filler cap o-ring missing or damaged

Faulty or damaged fuel filler pipe

Leaking, disconnected or plugged fuel vapor lines

Fuel in lines due to faulty rollover valve, on-board refueling vapor recovery valve or CCV stuck closed

Canister close valve clogged, stuck open or closed

Improperly installed purge solenoid valve

PCSV stuck open or closed

Faulty fuel tank pressure sensor

Leaking canister or catch tank

 

My car is sitting at the dealer right now. I spoke with them and they said they have come up with a couple things wrong a misfire, and bad crank sensor. Oy, I don't know what those are all about but I'm not liking the sound of it.

 

Where would the purge valve "sensor" be located?

 

God Damn it! You know what I meant. Must have just read that line in the post above the one I just did. Let me edit my last post.
