Has anyone figured out how to figure this one out yet? Been searching for days and all I find is, replace solenoid, replace sensor, replace hose, gas cap....nobody ever gets back and answers with a fix though. I've been through the whole vapor system and can't find anything wrong. More researching leads to it can be in the dpfe. How is that possible?

 

Can also be a leak in the lines. What did you replace?

 

I replaced the sensor, the solenoid, vapor can and the gas cap. I also pressurized the tank and checked the lines.
