4308 Evap close valve
 

I've got a check engine light. DTC is 4308.

To Troubleshoot I test closed the the evap close valve, and ecm fuel tank pressure did not move from .25

However whenever I close the valve I hear a buzz that sounds like it is coming from under the right rear wheel. It is not coming from inside the fuel door, and there is a new fuel cap on the car.

Anyone wanna shoot me some ideas on what to look at first tomorrow. This is all thats keeping this T-6 off the road

Btw, CarDAQ-PLUS and VIDA get along great!!!
