Need help with lb7 electric codes.

[Lyysergic]

2003 lb7 duramax throwing electrical codes: U1064, 1152, 1041, 1024, 1026. The issue is randomly, once every few days the truck might stall while in drive at a stop.

I've checked one of the main grounds on the drivers side chassis mount and it looks really good. I'm unsure of other location like how to find the ground from the firewall to the block?

Any other help would be great, thank you.

Also I do have an Edge Insight Cts2 for monitoring the truck and, now that I think back the issue has arrived since I installed the thing... Anyone else have an experience with them?

There is a ground on the driver back of head to firewall.

Checked that ground a couple hours ago. It looks like a really nice braided gauged wire, and the contacts had zero rust.

I would unplug this and see if the problem persists. Also check your batteries and alternator if you think you're having intermittent power issues.
