Title: Diagnostic help needed - P0446
Post by: Rogue on September 26, 2019, 08:17:02 AM

I'm trying to help a friend with a 2004 Saturn Vue 3.5 engine. Code P0446 won't go away. I found a stuck purge valve and replaced it, still kept setting the code. The gas cap was in sad shape and wouldn't seal properly, replaced it. Still setting the code. I'm now planning on checking the charcoal canister andd valve, but it seems I've always found that to set a different code (P0449). Does anyone know where I should be looking next?

Trace the hoses and inspect the hose ends/nipples. 

Looks like there are a few posts about this code on saturnfans.com after googling "p0446 saturn vue"

Would any of this help at all?

Good info there. Thanks. It describes the process better than most of the other articles I've read. A pity I don't have a Tech II or equivalent.
