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?

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.
