Mustang 2007 P0446 EVAP error
I'm new here, been driving my Mustang for a few years now and enjoyed it. It's running well, but I have had one problem for some time that I finally want to fix.
It's a (rather classical, from what I understand) P0446 Evaporative Emission Control System Vent Control Circuit Malfunction. Firestone tells me they want to run a smoke test for $99, but given what I found on the internet I don't think it's gonna reveal the problem. So I want to check if I can do it myself. I did a lot of googling already, but nothing seemed to match exactly my case.
It's a 2007 V6
P0446 is the only error code
I haven't noticed any problems other than the check engine light, which is why I haven't fixed it yet
Who can help me narrow it down?
I read to check the fuel filler cap, but I don't see anything wrong with it.
Easiest part to replace by myself is probably the vapor canister purge valve - good idea?
