We have a 2014 LS3 we installed a Kb 3.6L and ID 1000 along with long tubes and a nick Williams 102mm Tb.
Installed a drop in aeromotive fuel pump assembly for this car and we cant get the p023F code to go away. Don't see it in the Dtc area anywhere. We installed the fuel sensor back on car and got that light off this is a full return style system boost referenced mechanical regulator. Any suggestion on the Dtc?
I assume complete fpcm delete has been done? How is your setup wired?

The kit came with its own wiring harness assembly so nothing on car is used anymore! Basically standalone system! Like a fore kit but it's Aeromotive.Originally Posted by GHuggins
The fpcm is still on turned all codes off I could. But the system is not being used with a pulse width modulated system any more.
Steady 58 psi system 1:1 under boost
You have to unplug and remove the fpcm for codes to kill itShould be good after that... Something about it still having the ability to communicate ticks things off...

Thank you brotherYou have to unplug and remove the fpcm for codes to kill it
No problem, it's always amazing how the simplest of things like unplugging a connector can cause us the biggest headaches

I agree!
What are you guys doing to kill this code but keep the fuel pressure sensor working so that injector delta pressure can be monitored still?

commanded fuel pressure needs to closely match actual. tough with boost/vac reference, not so hard if you leave it unreferenced....
Basically you must use the fpcm to use the built in fuel pressure sensor... Meaning the only way to keep the p023f code from popping up is to power one of the fuel pumps with the fpcm. Not sure how the current output will play with the Walbro F90000274 but we are going to find out.
