Code. 62 is all I'm getting now. Had ecm 2 blow fuses. Fsd cooler from Green bay diesel. Misses like air in fuel. Like the mechanical pumps better. Like my 6.9, & DT 466, v8 deutz.

DTC 62 - Turbo Boost Sensor Circuit Low

A common miss cause is from the optical sensor noise filter-remove it and get some ferrite core from radio shack so that you have a piece on each OS wire when the harness is plugged directly in without the electronic noise filter.

I took it out and went from 4 codes to one. 62 but no 12. 3 of the wires had open copper.

You may need a new boost sensor but check the wiring?
Did removing the OS noise filter help with the miss?

When noise filter was removed works good but still have a 62 code Intermittent. And ecm b blows like a short. Any idea where it runs?

Have you checked the boost sensor that is screwed down to the upper intake and it's wiring?

ECM B fuse powers the ECM,the LP relay and LP near as I can tell.

Lp?
