my recent purchase 2008 coupe, engine light came on. Tested and it says evaporator emission system vent valve/solenoid circuit performance, no code.

My engine light is on, replaced cap, no fix, when tested by my GM retired engineer, it says, evaporator, emission system, vent valve/solenoid circuit. It looks like it is code P049, likely, but could be code P046. Anyone know an easy fix. For me it is likely a trip to my dealer, but sure don't want to spend big dollars. Any suggestions on what dealer costs would be?

Also does anyone have a good independent corvette mechanic in the markham area?

the code is actually P0449, not P049 or P046 S/B P0446

If the problems have been fixed, the codes need to be cleared.
(They may or may not clear themselves after a set amt of ignition cycles)
Buy / borrow an OBD2 reader.

There's this, or can tire, or princess auto, etc

There is a better than good chance that your issue is a failed evap vent solenoid valve. Easy DIY repair.

There is no easy fix, just replace it. I did it myself, as I recall had to remove passenger side muffler to get at it.

Thanks, considering all suggestions.
Was also given a local independent shop and likely will be taking it there.
Not working in my own cars anymore.

Champion motors was recommended and it was the Po449code, new solenoid and an updated harness fixed the problem, happy camper now and Champion Motors was great to work with.

you were right, Champion Motors put in a new solenoid and updated harness. YEAH!

Good news, the problem was P0449, emission solenoid circuit. Champion Motors (recommended by Forum members) fixed the problem, replacing the solenoid and installing a new harness (being recommended by GM). Am using Champion now for my C6.
