Anyone have experience with this code? I believe it's related to the evap canister from what little research I've done so far. Happened a few weeks ago and I just cleared it off with the scangauge. Came on a couple more times this weekend so probably gonna have to dig more into it...

i watched a few of those last night. seems like an easy fix and not too expensive. gonna have to try that when i get back from this work trip.

I started my H3 last week and while it was warming up, I was messing with the Burb (parked right next to it). I happened to have a cup of coffee sitting on the H3 rear bumper, and when I took a gulp...I heard three "clicks" come from underneath the rear of the H3. They were spaced about a second apart...CLICK CLICK CLICK. I thought to myself, "what was that?" Sure enough, when I jumped inside to leave...the check-engine light was on. It drove fine, and after 3 starts the light went out. I assumed it was a gas-cap issue and related to the purge solenoid. Its the only thing back there that could have made the noise. I'll keep an eye on it, and if I continue to have the CEL...I may have to get deeper into it. DW...let us know what you end up doing. I may not be far behind you.

from what ive read, its the solenoid/valve so that may be what you heard. i tried taking the gas cap off an back on too thinking it might be that. the good news is that the part is only like $30. not so for the colorado guys. their part # for that is more than just the solenoid and its $200-$300 so they figured oit they could just use the h3 one and get by for way less $$. im most likely gonna change the solenoid in a week or so. in Atlanta til thursday and racing my bike in the Tour of St. Louis this weekend. priorities.... lol

I had this code pop up a year ago. I had a garage replace this whole solenoid and canister. It's in an awkward spot between the body and frame near the rear axle. It ended up taking care of my code.

i bet that was a lot more expensive than a $30 part...
