Help with trouble codes??
Help with trouble codes?? https://ls1tech.com/forums/pcm-diagnostics-tuning/697882-p0440-p1626.html
I started a thread in the diagnostic section, but I thought I'd try here too.
I've found out it could be my gas cap, or a couple other things. I was just wondering if anyone has had any problems, or luck with these two codes?

The theft deterrent system code blips when the VATS system shorts out, could just be a quick voltage drop for whatever reason. When you reset your SES light, that one should go away (unless you actually have a VATS issue).
Have you tried resetting your SES light to see if they come back?

Yeah, I cleared the codes today and they didn't come back up for 30 minutes I drove it. I hope that it was just a drop in voltage.
Thanks for the help. I had to mess with the fuse panel last week, maybe I turned the key on with a fuse out?
