Fuel Pump Control Module Codes?

[Jcarrig3]

Anyone familiar with these codes:

P025A Fuel Pump Control Module Circuit Open
P1206 Fuel Pump Control Module Open Circuit to Fuel Pump
U0109 Lost Communication with Fuel Pump Control Module

My check engine light came on, I have tried checking and pulling fuses. That seemed to get rid of the codes, but they came back. I don't notice any hesitation or other indication that the Fuel pump is failing.

Does anyone know what this might be, or better yet where the Fuel Pump Control Module is on the 2018 3.6L?

I've been getting the same over last few weeks, car won't start. I think I've narrowed it down to a bad connection at the fuel pump fuse.

On a Facebook group, someone mentioned the green star connector (can bus) block behind the glove box as another possible place for a bad connection.

I have not had time to investigate that one yet.

Did you ever resolve this? What was the fix?

Did you ever get this fixed? What was the issue and resolution? Any info would be SUPER helpful.

Sorry, I just saw this.

It was a short with the ground wire to my fuel pump. The dealer replaced the wire harness.

Not a short, surely. An open.

Yeah, I probably got the wording wrong.. either way, it was an issue with the wire harness.
