2018 Ford Edge - P1450 Unable To Bleed Up Fuel Tank Vacuum

- In this video, we delve into the intricacies of diagnosing and fixing a P1450 trouble code on a 2018 Ford Edge. Using the Snap-on Zeus+ scan tool, we embark on a journey to uncover the root cause of the problem. Our diagnostics reveal a concerning issue - the fuel tank vacuum dropping excessively, triggering the vent valve to open and safeguard the system. Even disconnecting the purge solenoid's electrical connector fails to mitigate the vacuum drop.
Through meticulous testing, we pinpoint the culprit: a faulty EVAP purge solenoid, leaking vacuum even when unplugged. Armed with this knowledge, we procure a genuine replacement from the dealership and proceed to install it. With bated breath, we retest the system, and success! The Ford Edge's EVAP system is now back to optimal operation.

I like the way you isolate each arm and test both sides to verify the diagnosis. When I read the schematics on these systems I get confused by all the check valves that can mess up the logic if you're driving pressure the wrong way to plug a check valve.
The import systems are the most confusing for me and I think it comes down to the imports not failing often. Most of the import have the ability to isolate the canister from the tank during testing but I always need to reference a book from ATG that really breaks down each system and how to test it efficiently.
the power and convenience of today's scan tools
nice to see you back in the saddle, Chad:)
Good morning Dennis. I wish all manufacturers would follow suite. Nissan is still one of the worse when it comes to usable data on the scantool. Even with the OEM scantool I was unable to see variable valve timing data on a 2017 infinity v6. Domestic vehicles typically offer quite a variety of data to sift through
Hello Chad,
If your body ever decides that it’s time to put away the tools, you would make one hell of an instructor. The way to present your thought process is superb. Thank you!
Thank you Dave. I tried teaching at the college/high school but it seemed that 2 hrs a day away from shop was too much. I may start teaching at events in the future which will only take me away from the shop every couple of months.
Nicely done!
Thanks. I love when the scan tool has the functions needed to assist in the Diag process.
Good to see you're back to posting videos since we talked at vision
It was great eating lunch and BSing with you at Vision. Sometime I need an event like that to kick me in the rear and get me to make some content. Have an awesome week Jerry.
You too!
Thumbs Up...Chad 😁👍 Nice work Bro.
Thanks Kevin!! Nice to hear from you!!
In the back of your mind, are you factoring in fuel level and temperature when assessing the response time with the pressure change value?
Thanks, great tutorial as usual!
Absolutely. If the tank was above 3/4 it’s possible that the scantool would have denied the bidirectional control of the vent valve. Most evap testing is performed between 1/4 and 3/4 tank. If the tank is empty the vacuum pulldown takes longer. Fuel temp is another consideration, a hot tank will vaporize fuel quickly especially when a vacuum is applied causing the vacuum decay to be quite rapid even if the system has no leaks.
If you do alive data with the scanner.Will the purge valve turn on and off every five seconds or so or should it be steady linegraph
At the end I show what it should look like. If the purge is kicking on and off that rapidly you may have a leak in the tank, cap or vent solenoid. The purge is kicking on and off in an attempt to maintain a vacuum in the tank for testing.
