HEST light on too often...

[Brock]

I've got a laptop with insite up and running now so it's time to figure this out....

Whenever I slowed down ad the exhaust temp light came on, I would get white smoke from under the hood. smelled like diesel. .. one of my exhaust gaskets for the doser was rotten out so I replaced it. bo smoke but problem still exists.

I'm wondering if the exhaust and constant regen may be related to the vgt code I am getting and am curious about what dbl overdrive said about the sensors...

I've got 2 questions.

To test if the sensors were causing issues from loose connection as stated... could I run a regen and wiggle wires to see if it cuts out anything?

Can I test the vg calibration with the actutor on the turbo? I've seen the videos on how to calibrate it but was wondering if there's any way to know if the calibrations the issue before removal? or do you just start from scratch...
