Great video! Replaced the purge valve a couple of weeks ago due to not wanting to start after filling up with gas, and thought all was good - now getting the P0456 code.

2016 Ford Transit Connect...Ended Up Being The Purge Valve Solenoid Has A Vaccum Stuck open while the Engine is Running.. Replaced part.

I have a 2019 Ford Escape and my engine light came on at 65k miles. I go to Midas and they told me I needed my fuel injection system cleaned. I Paid like 600 bucks when that was my code. And guess what 3 days later my light was on again! Autozone said I needed some gadget and it was only $75. So now I have to go back to midas and if they have the audacity to tell me now I need the piece to fix the small leak I'm going to be mad! They charged me 600 for something I probably didn't even need!!!

[@jorgeurbina7810]

Fuel injector cleaner costs like $15 and all you gotta do is put it in your gas tank you got scammed like crazy

If my car had an O2 sensor issue that when untreated cause it would pop on and off with no reasoning.... should i start there before replacing the valve?

[@HVAC_Mechanic]

Usually, a 02 sensor and EVAP problem are separate issues. If the purge valve is stuck open, it may affect it.

[@moniquehernandez778]

If smoke is coming from the hose, is it safe to assume a new hose is needed?

[@brandonpizzoferrato9361]

Yes

Purge valve solenoid at the charcoal canister in rear of vehicle

[@Heavy69Metal]

What happens if you cannot start vehicle yet you had the P0456 code

[@HVAC_Mechanic]

If the purge valve is stuck open it can cause issues sometimes, but it will not stop the engine from starting.
