gas cap fault but not gas cap

[agood01]

Gas Cap Fault, We have a gas cap leak fault but the gas cap was replaced and did not make a difference. We did a smoke test and the only smoke we saw was out of the fresh air assembly next to the fuel fill hose. Don't know if that should have happened but that was the only leak. Also I can't find where the fuel vacuum pressure sensor is. Any help would be great.

You try to pinch of the hose at the vent valve hose and see if that will pressurize the system and check for leaks that way. What year of KJ do you have?
