Nebor Posted March 23, 2005 Report Share Posted March 23, 2005 I tried changing my gas cap, but this code reemerges once a week or so. Any suggestions? Should I try changing the Evap canister? Or should I just pony up the $600 to replace the whole pump assembly from IPD? Link to comment Share on other sites More sharing options...
Nebor Posted March 23, 2005 Author Report Share Posted March 23, 2005 Anyway to just trick the sensor that reports the status of this system? Link to comment Share on other sites More sharing options...
Bay13 Posted March 23, 2005 Report Share Posted March 23, 2005 You have a gross leak. The car runs a test after it is warmed up and about 12 minutes after start up. It tries to run the test until the ignition is shut off, every key cycle. If the gas cap is on correctly, then you need to find out why the test fails. Could be lots of thing. A hole in one of the lines cause a critter chewed through it, could be a bad Canister purge valve(also called the EVAP valve). Link to comment Share on other sites More sharing options...
550 Posted March 23, 2005 Report Share Posted March 23, 2005 Oh yeah on our blazer a freaking animal chewed the lines on that... what a pain in the butt. It could be something completely unrelated like rich said the gas cap. You woudlnt think about that but it can throw codes because the system thinks there is a problem Link to comment Share on other sites More sharing options...
WhiteT5 Posted March 23, 2005 Report Share Posted March 23, 2005 Hehe, reminds me. On our Honda, a rat got up inside the engine compartment and made it's way over to the serpentine belt area. This is when the car was like almost brand new. So anyways, someone went out and started the car and the sound was something like "squeak squeak, thunk, clunk" and then the engine died. Apparently, the little booger was chewing on the serpentine belt when the car started. It got towed to the dealer and they denied our warranty stating that "Honda Motor Co. cannot be held responsible for small creatures causing damage to the vehicle". Hehe, OK. Now, to address the problem, Jeff, you didn't buy an aftermarket gas cap, did you? We've tried those before and they always trigger the check engine light.

MrWinkey Posted March 23, 2005 Report Share Posted March 23, 2005 It's warmin up ..."Critter Season"....man can those ground hogs be destructive little bast#rds!...Did you replace the gas cap with a factory one or a Pep Boys special. Like Rich stated you have a huge leak Link to comment Share on other sites More sharing options...
Nebor Posted March 24, 2005 Author Report Share Posted March 24, 2005 I replaced it with a local auto parts gas cap. Damnit. Link to comment Share on other sites More sharing options...
Vitor Posted March 24, 2005 Report Share Posted March 24, 2005 I cured my P0455 on my wife's 98 V70 by cleaning up the dents on the filler neck caused by hitting it with the gas nozzles.Also, I cleaned the purge valve, it is located on the top left side of the fan shroud.

Nebor Posted April 3, 2005 Author Report Share Posted April 3, 2005 I spent 2 hours looking for the "Purge valve" last night. I read reports that it's located right under the air intake tube. I need some kind soul to take a picture of their purge valve and it's location so I know where and what it is. Link to comment Share on other sites More sharing options...

Bay13 Posted April 3, 2005 Report Share Posted April 3, 2005 OK the below link shows where the purge valve is but yours will look different, more square than the one in the Pic. Link to comment Share on other sites More sharing options...
Nebor Posted April 3, 2005 Author Report Share Posted April 3, 2005 Ok, yeah, I looked at that thing quite a bit, since it was in the proposed location. But attempts to follow the lines coming out of it proved to be fruitless. Where's the evap canister that the line leads too? Should I mess with the valve? Replace it? Or what?

Bay13 Posted April 3, 2005 Report Share Posted April 3, 2005 I'd replace that valve before going further, they are known failure items. Link to comment Share on other sites More sharing options...
Nebor Posted April 5, 2005 Author Report Share Posted April 5, 2005 I'd replace that valve before going further, they are known failure items.←Ordered one from FCP Groton. About $60 after shipping. This combined with the "known failure" ABS module is not making for a great first month of ownership. :angry: Link to comment Share on other sites More sharing options...
