Stop engine light quandary?

[Bmyetrkg24]

Thanks for the input guys sorry I'm late getting back on here its not the plug or sensor as far as crankcase issue Mr rawze the red stop light turned out to be a dead wire on the throttle sensor between the oem motor harness on motor and the firewall we got that fixed and did a force regwn took about an hour thought I might be in the clear took off drove for 3 hours crankcase light on again turbo cough throttle lag slightly seen a little smoke so I knew what that meant it was trying to regen again already so I hit the button on dash and it started a regen lasted 6 minutes then failed at this point I'm guessing turbo is failing aND pumping the crankcase full of air and the egr side with soot and it can't regen because of the junk turbo unless u think theirs something in this already skeptical harness which I have ordered thanks for the vine fellas
