P1450 unable to bleed up bleed fuel tank vacuum/excessive fuel tank vacuum. Just popped up on the dash. I've been having issues with the truck stalling at idle and some really rough idle but no issues when I'm giving it gas. I've been thinking it was cam phaser issues since it sounds like a diesel when the idle gets rough. Anyone have ever have the same code?
Is that some EPA mandated carp to prevent gasoline vapors from entering the atmosphere, pulling a vacuum on the fuel tank?
It could also be a vent line from the gas tank is plugged up. As you use the fuel, you pull vacuum into the tank, eventually starving the engine of fuel. Check to make sure all the vent lines are clear and in good shape.
Y'think FoMoCo would have used hard vacuum line on that side to prevent collapse of line causing hard vacuum to the tank. Hate to think you'll have to drop the tank to diagnose this one.
Yea don't say that haha Used my buddies shopkey log in for his students, there is a TSB on there for the 2010s with my exact code, they say to replace the evap purge solenoid after performing a visual inspection.
Well for your sanity let's hope that solenoid is up front in an easily accessible location in the engine bay. Galaxy S4 Cetane Powered Android
Haven't had a chance to really dig at it yet, probably won't till Saturday. Messed with some hoses yesterday, checked them out and made sure connections were solid. No CEL or code this morning BUT I refuled a bit ago, had to try 3 times to get the truck to start. Another symptom of a bad purge valve. Hope I can get one this weekend.
