| spn 1231 Need help with a Paccar px-8, is throwing code spn 1231 and while driving turbo often chuffs/sneezes when under a load. I replaced turbo because selector gear was stuck and wouldnt pass the vgt acuator test, and thought this was causing the sneezing. With new turbo it has the same problem. No check engine light, but its giving code spn 1231... any advice?? 2012 Pete 348, 150,000 miles, all local. i got DPF, DOC baked/cleaned, replaced egr valve | |||
