I just wanted to thank you for posting this and making it a how-to. I had the P1444 code, so I went and got a fuel filter and put it in-line. There was a lot of charcoal that came out of the purge valve and the line actually had a charcoal blockage, so I got that cleared, then I started my Pathy up and the SES light didn't come on!!
Eventually I'll have to replace the canister and blow the line out, but I needed a quick and dirty fix right now so I can pass my smog test before this week is over. The SES light coming on a few days ago couldn't have been at a worse time, but reading about the solution here was great. The best part is I didn't have to take it to the dealership and pay out the nose to have them fix it.
Thanks again!!!
