We repaired a head gasket/head bolt failure. After reassembly, we are experiencing a DTC PO340 code, a ground wire problem for the IC Module.

Please advise as to where we locate the exterior ground, the manual shows it located at right backside of engine at ground 102. We cannot find it.

Thank you!! Diane

I'm guessing the ground is the mounting bolts, but year and model would be a big help. add it to your profile and we won't have to ask if you forget to post it.

BAck of the valve cover where the coolant tube bracket goes, there is a ground wire leading the same location, It should be in the middle of the cylinder head. No worry though It merley attaches from the coil bracket, (bottom right) to the head but you could easily make another ground wire to a diffrent location.
