Post by 2015jeep5.7 »

So i installed the unlocked pcm and t2 today, and now I'm getting dtc of P2008 and P2016 along with the abs lights for some reason. I'm not sure why? I cleared the codes, but they came back immediately. I hope to hear get some answers?

so you got both codes before even tuning?
Just from the pcm installation?

did you do anything else when you installed the pcm?
Is it possible you damaged or bumped the intake runner control connections?
Both codes point to that, so I would probably start there.

It would seem that way. Unless there was a loose connection somewhere.
Can try swapping it back again to confirm or give our guys a call to troubleshoot it, 561-908-0040
