Default P0456, P0457 2005 Ram 1500 5.7l
I have a 2005 Ram 1500 with the 5.7l Hemi. I keep getting the p0456 and p0457 codes. I have replaced the gas cap and evap pump. I had it smoke tested and there were no bad/ cracked hoses. The only leak that was found was around the fuel tank vent valve. How do I replace or fix this problem? Thanks!

I don’t know, what solenoid are you talking about? I have switched out the fuel cap and the evap pump.
