P023F on 2010 Camaro

[Wolverine]

I've bypassed the FPCM on a 2010 Camaro to drive twin Walbro 255s. Now we get this code P023f fuel pump circuit open (or something like that). It must be coming from the body computer? Because that code doesnt show up under the list of DTCs. Anybody else ran into the same problem? Could some of the tables in the fuel system menu need to be changed to make this go away? Thanks, John

Hello Wolverine,

Have never tried this …

In the folder Fuel System / Fuel Pump / Parameter - set F0585 (FSCM Fitted) to “No”. Might also try setting DTC P0230 to “Not Reported”.


Regards,
Taz

Hey Taz, I set all the parameters/dtcs like an e38 without FPCM. I got a suggestion from someone to simply unplug the FPCM, seems like the code might be set by the module itself. I'm gonna try that tomorrow and let you know. Thanks for your help!

any updates??

[Wolverine]

Yes, simply unplugging the FPCM fixed the CEL. I thought doing that might throw some other weird code from another module, but all is good!

I wonder if this would work on all in take fuel pressure regulators. Where was yours located?
