Got the above code along with 3 others. Fixed two of the problem codes (had both upstream HO2 replaced $$$) and still have two codes remaining, this being one, the other is an IMRC stuck open.... In any case, what is the position of the camshaft used for in the EMS and will it trigger a CEL. Any info would be appreciated as well as any help with the freeing-up of the stuck IMRC.
Thanks!
