Does anyone happen to have a fuel pressure sensor pinout available?

I bought a 2008 Cobalt for my daughter’s first car and I’ve been chasing a P0452 (low voltage) code for a while now. I found the wires were severed from the connector, so I went to the local junk yard and grabbed a pigtail, spliced the wiring together and installed. Code persisted. I then replaced the fuel pressure sensor, with no change. I thought maybe the aftermarket sensor was the issue, so I ordered an OEM one and swapped it out. Same code. I checked voltage and I’m getting 4.xxV at the connector, but I’m questioning weather the wires are in the correct order, as it seems every video I see the wires are in a different order. I tried swapping the wires to match a 1A Auto video for changing out the fuel pressure sensor, but that didn’t help either.

Beating my head against the wall on this one and would appreciate any assistance.

Glad to see someone post on this site.
I was beginning to think this site was dead.
It might take a few days, but I will check to find what I can with the information I have.

Glad to see someone posting here, I was beginning to think that this site had died a slow death.
