Hey guys i have my personal 2008 chevy tahoe that’s a turbo truck and i had bypassed the stock fuel system with fuel lab regulator 8an lines and dual 450s with two separate relays to power them. the stock fuel pump assembly is still plugged in like usual i just tapped into the trigger wire to kick the relays on and now i have this code p023f which does nothing trucks fine and i don’t mind the cel on mostly cause my remote start still works. but i’ve been messing with the fuel pump dtcs to see if i can make it go away since that exact code you can’t just put no error. but nothing comes right back on is there anything you guys do to bypass this? i may or may not need to pass smog haha only reason why it came to my attention thanks. still has oem cats and does not have a 4in downpipe exiting behind the tire

 

P023F is in your fuel pump control module, you will need to read that out and disable that code separate from you ECM.
