Hello, the first code is with the idle air control valve circuit. Inspect for any vacuum leaks, especially in the pcv system and valve cover to air inlet tube at the throttle body. Clear the codes and recheck. If the same codes come back, Clean the throttle body if there is carbon build up. Otherwise go ahead and replace the idle air control valve. The second code is saying the keep alive memory for the powertrain control module voltage is low. This may be caused by the need to reprogram the PCM. Or the pcm itself is having an issue. Reflash it first if the code comes back and retest before replacing the pcm.

I checked it out their was a blown fuse
And it idles ok. I tried to clear the codes
But it still says check charging system
Ford Mechanic: HDGENE, Ford Senior Master/Diesel/Trans replied 7 months ago

Still says? I dont see any mention of a charging system issue? Is it charging? Was anything replaced for the charging system ?

The original problem was the serpentine belt broke and the battery went dead
So I had it towed home
But it said check charging system
Before that happened and that was one of the codes But it is charging
I tested it. I think that is the pcm code
The 2nd code and problem with the idle
Went away when I replaced a burnt out fuse.
Ford Mechanic: HDGENE, Ford Senior Master/Diesel/Trans replied 7 months ago

Neither ode is for a charging system issue unless there is another code stored ??? What caused the belt to break? You replaced the serpentine belt and its charging but it says check charging system?

I tried to clear the code but the check charging system still shows on the dash
But I get no code with my code reader
And the battery light still lights up in the dash
Ford Mechanic: HDGENE, Ford Senior Master/Diesel/Trans replied 7 months ago

Ok, if its charging but there are no codes ut the battery liht stays on, then there is most likely a bad diode in the altenator and that will need to be replaced.

I need a new altenator
Ford Mechanic: HDGENE, Ford Senior Master/Diesel/Trans replied 7 months ago

Thats what it looks like, the pcm controls the charging system. Long as the altenator is getting power then one of its diodes is bad and the altenator needs to be replaced.

Because of your expertise, you armed me with enough ammunition to win the battle with the dealer. They are installing a fuel filter and fuel pump at no charge to me.

I do know, after going though this with JustAnswer, that I can somewhat trust my mechanic but I will always contact you prior to going there.
