Ford P1450 Fuel Tank Vacuum "Most Common Cause" & How to Test

Customer Concern: Ford P1450 Fuel Tank Vacuum "Most Common Cause" The Check Engine Light (CEL) is on and the Powertrain Control Module (PCM) sets Diagnostic Trouble Code (DTC) P1450.
Fuel Tank Emissions Vapor Canister Purge Valve Solenoid Assembly w/ Hoses & Bracket Fits 2013-2014 Ford Fusion: amzn.to/2EklIHh
Pocket Scan Tool: amzn.to/2JmtJ24
Tests/Procedures:
1. Check the canister vent solenoid and related hoses for any restrictions and repair as needed. Be sure the canister vent solenoid is open at rest as it should be.
2. If the solenoid and hoses are OK, access the charcoal canister. Verify the canister is not restricted. Replace as needed if it is and recheck operation.
3. The purge valve is a normally closed solenoid. Verify it is not stuck open and applying vacuum to the fuel tank.
4. If the purge valve checks out OK and the canister appears free of any restriction, remove the fuel vent hoses as close to the fuel tank as possible. Check the hoses from the tank forward for any restriction. If the hoses are OK and no external restrictions are found, suspect a possible problem with the fuel tank vent valve(s) in the top of the fuel tank.
Tech Tips: Anything that causes a restriction in the venting of the Evaporative Emission (EVAP) system can cause a code P1450.

You need to hook up the vacuum gauge to the engine side of the valve. Not all are designed to hold vacuum both ways, this one included.

The wrench indicator light came on and would go on and off for about a month and even when on wouldnt throw a code but after a month the check engine light came on with it and it was the P1450 code. I changed the purge valve, cleared the check engine light and it has yet to come back on but since the wrench indicator light has come back on im wondering if it even fixed the problem?

I drove to the gas station to get gas and the car wouldn't start. So long story short i has to get the car towed today to the mechanic. Could this happen if someone put something in the gas tank.. These cars don't have a locking gas door. I came out Sunday morning and the gas door was open. just a crack. thanks in advance

[@Xsiondu]

You probably got it fixed but that could be from the valve being stuck open and filling the tank pushed extra fumes into the intake and made it too rich to start

I tested the purge valve by blowing into it. It was letting air go through! I replaced it! I'll let you know if the code doesn't return.

[@brandonquinn6176]

Did it work out for you?

[@Movieman1965]

@@brandonquinn6176 Hello. It worked very well indeed! It turns out it was causing a few problems besides just check engine light. The car would stutter/shudder at 40-45mph before I replaced the purge valve. Also, whenever I filled the gas tank from empty the car would experience a hard starting process where it would crank a long time to start up ( if it was say 1/2 tank with gas it wouldn't happen). After replacing this purge valve all those problems disappeared. Oh, and prior to this the idle was always rough and sometimes the engine would shut off too! No more shudder at 40-45mph, no more hard starting, AND I have not had the check engine light return since that time. It's been about a month now. BTW, I replaced the spark plugs and they really looked chewed up bad! I also replaced the ignition coils. I also replaced the A/C Pressure Switch ($25 part easy to replace) because the A/C had a good charge but it was not engaging the A/C clutch. It solved that problem. I also replaced all the fuel injectors (easy to do also, time consuming but easy, cost for the injector set of 6 was $70). I also cleaned the Mass Air Flow Sensor ( You just spray the brick colored resistor with Mass Air Flow Cleaner Spray, not expensive). I also replaced the Throttle Body ($73, easy to do also). The reason I replaced so many things is because my 2013 Ford XLT Explorer has over 125,000 miles. I didn't buy it new so after checking it appears these parts needed to be replaced to ensure reliability. The only thing I plan to do now is get the Rear Suspension Toe links replaced at the dealer tomorrow because of the safety recall (19S17). They say these can break and cause loss of control which may cause an accident or worse! I did go look under the rear of the car to check if mine were cracked or borderline but I did not see anything wrong. But, after closer inspection I could see that the way these Toe Links were designed it's just a matter of time before I run over enough train crossings to cause a fracture and then maybe I crash into something! I also took close-up picture for my archives. I will be also marking them later today and taking pictures again to make sure that they are actually changed as the recall dictates. Anyway, at this time the vehicle is running very well, acceleration has also improved. I may look at the vacuum lines next for any leaks. Ok, that's pretty much it for now. I hope this helps of you with 2013 Ford Explorers out there. Now that I think of it, the steering power assist rack and pinion had also failed about a year ago (Ford did not have my VIN in the recall, some others did). I had to muscle steer the car for a month before I found a dealer to replace it for $2,000 with warranty. Also, now that I recall further, last summer the A/C condenser had a leak. Replacing it cost another $2,000 because it is hiding behind the dash (labor was the biggest cost). Anyway, I can say since purchasing this car used with 76,000 miles I have spent about $5,000 to get it working properly since then. Have a great day!

The purge valve isn’t designed to have excessive vacuum pulled on it that way. The EVAP system works with less than 1 psi. Proper way to test the purge valve to pull vacuum on the intake side of it. Just FYI.

If not repaired, what are the effects on the vehicle besides the CEL?

[@FlatRateMechanic]

There could be a few adverse effects. Basically, if the purge valve is leaking that means the engine is pulling unmetered air which can affect drivability and fuel mileage. And with the purge valve leaking, that means you are pulling a vacuum on the fuel tank and if the vent valve fails for some reason you could clasp your fuel tank. Seen it happen.

A stuck open purge valve may/may not be noticeable so depends on how bad yours is. May idle high, surge, or stall out at idle; or impact may be negligible.
