Hi, Recently bought Dodge Journey.
My gas cap, Engine light came on. P0456, small leak EVAP.
I replaced with off brand gas cap and off brand Leak detection pump. Still the same.
Didn't check yet the purge valve.
I was wondering. I check the fuel tank pressure and i see .99 inH2o. But my fuel tank pressure volts shows NA.
Would that cause an issue?
I assume the volts have to be there. How can i check? Any wiring diagrams available?
Thank you for the forum.
