2006 5.3L automatic 4x4 crew cab 1500
P0446
I'm due for emissions in my state in late June.
So far I have:
Cleaned the evap breather filter
Replaced the evap canister solenoid
Ran it for several days same code popped back up
Next round:
New gas cap (old one's o-ring was all cracked up
New evap purge valve on engine.
So as far as I know what is left of the EVAP system is the charcoal canister, the pressure sensor on top of the gas tank and possibly a cracked evap line?
Is there something I'm missing or over looking?
Also if the charcoal canister is the most likely culprit it seems rock auto has one for $63 while the local parts store is almost $200. Is there really any difference in them?
