I'm having 2 codes come up p0740 and p0785. I've looked them up, I know what they mean. But could somebody tell me what this combination means. And how can I fix it?

 

They together mean nothing.....u should always start with the first code that stores in memory diagnose that first..., often times the first issue causes the ECM to store other codes as a result of this 1st issue at handp
