Quick question

[96stroken and smokin]

Last week I scan my truck for dtc and p0272 and another code for 5 or 7 can remember right off hand. I clear them they immediately come back I drove it and scanned it the next day they cleared and went away for the day. So I'm getting them intermitted. Sound like the ficm?

Could be, Did you check FICM voltage?

 

[96stroken and smokin]

No I was planning on going down to holderdown here in a few weeks and take the ficm with me and get a new one and hope that fixes it. If I get time this week I will. it will probably sit for a couple weeks

No need to replace the FICM if it isn't bad. That's a good chunk of change to most people haha.

Check to FICM before, there are usually quite a bit of good how-to threads on here about going about that. Should never fall below 46V when cranking, at idle and with key on engine off.
