This morning I noticed a warning light that came on on my dash for the emission system. I pulled two codes from my Edge
1.)P0138 (hos512 circuilt high voltage)
2.)P2271 Sensor Signal Stuck Rich Bank1 Sensor 2.
I'm more worrried about this second one. I returned the truck to stock and the warning light went off. I was running Level 2 on my Edge, with no changes made to the timing. Now I haven't downloaded a new version from Edge since last summer (right after I installed it) do you think this could be a fix for it. Or do you think I should contact Edge?
I think Edge will help you through this one. You should probably try downloading the latest software and see if that helps. You probably should do it anyways so it can't hurt to try.
