P0403 error code

[XFACTOR7]

Anyone ever deal with this DTC code before?:eek:

whats it on??? they're are reflashes and procedures that cover this in TSBs. Also could need an egr valve if the items covered in the tsb do not correct the issue.

Apoligize for the lack of info;

I have a 2007 GMC Sierra 3500K Classic w/6.6 Duramax, the one and only engine worth a ****.

Some more info: this started after the battery went dead on the drivers side and had to replace it.

Could this mean a reflash is in order as the DTC lost info?

I do have a Actron Elite Scanner (cp9185) model.

Excuse my lack of knowledge but what is the TSBs?:o
