02 I35 P1448 and P0455

[tgorenc]

I got a car wash last night and my service engine light came on in my 02 infiniti i35. I put a scanner on it and two codes popped up.......

1st code-P1448 EVAP canister vent control valve

2nd code-P0455 EVAP control system gross leak detected

If anybody can tell me on what to do and how to do it i would really appreciate it

Thanks

Tom
