^Do you tighten it until you hear a few clicks?

 

EVAP Canister Purge Valve. (http://techinfo.honda.com/rjanisis/pubs/SB/B09-056.pdf)

I replaced mine couple weeks back and it's gone. Interesting note, the part I pulled off was made in Mexico had a MEX in front of the part number, the part I put on was made in Japan.

 

I have the same problem. If car is not under warranty you will be looking at $150 to fix at Acura.

 

or you can buy the part for +-80$ and change in 10 minutes by your self.

 

Id perfer that. is there a DIY? saves me a trip to the dealer

I thought that the evap canister would be covered by the 8 year/80K mile emissions equipment warranty. Warranty would likely apply to OP's '08 TL.

 

They checked mine & said they fixed it, no charge. It's come back a couple weeks later so I'm going to buy the part & change it myself.

 

I have an 07. from my understanding its 7 year 70k powertrain. I will call my dealer and find out about the emissions warranty.

 

This part does not fall under Emissions warranty. Says right on the TSB.

 

Mine does this too. Im still under warranty so ill send id by acura. Mine does it when thr fuel light comes on.

 

Yes, you're correct: it just says "Normal warranty" applies on the TSB.
Hopefully that still applies for OP.

Although various other emissions control parts are covered for 7/70 or 8/80 by the emissions control warranty in CA, the only Evap System component covered--7 years/70K miles-- is the fuel tank.

BTW, in order to view any TSB, we have to go to the TSB sticky thread and go through the selection steps before a TSB link will work.

 

I tightening my cap till it clicks like 5 times... it occasionally turns on...stays on until i get out of the car loosen the cap and tightening again...

at first it doesnt bother me but the beep beep beep got to me pretty quickly...

 

Umm.... you ever thought of just replacing the gas cap? 5-10 bucks.

 

i figure it was some kind of sensor...i went to get an inspection...the guy said my gas cap was ok...

but who knows...ill try this route anyways..5-10 bucks? why not??

 

It's worth a try but I strongly doubt it. Look at the TSB I posted and see if you have the symptoms listed.

 

your post on 3 keeps giving me error..link deny

Known issue with the gas tank vent valve. Dealer fixed this for me quickly and for free after I mentioned the TSB.
