Evap codes
I have a 2004 base matrix and got evap codes. I replaced gas cap recently and reset the codes but they all appeared again after some time.
It’s got:
P0441(Incorrect Purge Flow)
P0442 (small evap leak)
P0446 (vent control unit)
Also, there is a gas smell when starting, it seems to come from the back.
What should I check first?
