anybody have the problem I have? My car is an 08 Z with 6500 miles and I already got a P0455 code which states I have a large emissions leak. Wondering if it can be caused by my exhaust system or if it is just a faulty part.

Thanks in advance

 

EVAP isn't related to your exhaust at all.

First, since your car is so new, check to see if the fuel cap is tight. If it is, then the leak is coming from elsewhere.

The evap system monitors and manages your gasoline gas (fumes). There's a carbon canister usually located in the engine bay, but may be located under the fender or the rear of the vehicle. This canister runs lines to your fuel tank. Trace the lines to see if there are any leaks. Also check your fuel filler neck to see if it has any cracks. It's also possible that a tee on top of the fuel tank has cracked. There's a lot to the EVAP system, just have to trace and see what you can find.

 

That code is actually related to the EVAP Purge Solenoid. It's mounted on the plenum on the back passenger side. Make sure the harness isn't disconnected or the rubber hose hasn't come off either end. The solenoid could be bad too.

 

you have a huge evap leak if your gas cap is loose it can do that
