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.
