theexbrit Posted January 27, 2014 Share Posted January 27, 2014 I need to do the wiring harness mod as I'm getting intermittent p0156 & p325 codes, I think it's the ground problem discussed here & before I go buying o2 sensors, etc, I'd like to try this. The links are all broken, does anyone have the TSB &/or photos of where to mount the harness? One post I was reading on another forum the guy said he used the wrong bolt holes & it didn't help with the problem until he used the correct bolt holes on the manifold.

tmjayat Posted May 7, 2014 Share Posted May 7, 2014 Hello guys I'm new to the forum but I just checked my voltage drop and it was reading around 150 mV . I put the red lead on the grounding bolt and the black on the right side cylinder head as instructed. Anything I'm not doing right, or is this a likely thing? The engine was running idle after a 8km drive. Link to comment Share on other sites More sharing options...
