so i had code p0451 for fuel tank pressure sensor range/ performance. i replaced the sensor and had the code cleared today but i gotta feeling the code'll come back :/ someone lmk if you've had this code and wat the definite fix is ;D i have no other codes wit it

 

ill repost to this in a couple days if that was the fix for anyone whos got the code p0451

 

Fixed!!!!

 

 

In going to guess changing the sensor did the trick

 

on my 08 ss it was the purge valve n on my 09 base model it was thefuel tank pressure sensor. mine also snapped off the charcoal canister lmao
