Ford F150 P1450 engine code

What does the Ford F150 P1450 engine code mean?

The P1450 engine code is “Inability to bleed up fuel tank vacuum.” This may sound a lot scarier than it seems, but it’s not something that can jeopardize your truck Your car is either having a hard time dealing with fumes when running or has more fuel than it can handle.

Alright, the P1450 engine code. There are a couple of ways you can try to solve this issue.

As usual, I’d go from easiest to hardest option. The easiest way to tackle this issue is to assume you went a little wild on the gas pump a few days ago and overfilled the tank.

Did you have trouble starting your car after filling the gas tank? That could’ve triggered the P1450 engine code.

If that didn’t solve your problem, I’m going to explain in more detail the other possible reasons. Don’t worry – they’re not that bad!

Worst case scenario, you’ll have to replace a worn-out cap or a canister.

So, yes, the P1450 code is not a life or death situation for your car, but small problems tend to grow when left unattended.

What is a fuel tank vacuum?

A fuel tank vacuum often occurs when oxygen can’t flow properly in your gas tank. When that happens, your car will have a hard time starting – up to the point of not being able to get the engine going.

In simpler terms, a fuel tank vacuum happens when your gas tank is unable to breathe properly. Oxygen flows in and out of your gas tank the same way fuel does.

Sometimes, the fumes from the fuel will get stuck inside. After a certain point, there will be way too many fumes trapped in your tank, thus creating a vacuum of sorts.

Other times, fuel will flow out but nothing will come in. So, without proper oxygen circulation, a vacuum happens.

This second scenario often occurs when you have a worn out gas cap or a faulty hose. A broken or clogged canister can also cause this to happen.

Fortunately, a fuel tank vacuum is easy to fix. Remove the gas cap and allow the fumes to go out and air to go in.

Now, that’s only a momentary fix. You need to sort things out permanently unless you want a vacuum to happen again.

How can I fix a fuel tank vacuum?

There are different ways for you to fix a fuel tank vacuum depending on the issue you have. As I have covered above, you should first try to see if you didn’t go overboard last time you filled your gas tank.

Other than that, check your gas cap. Then, the fuel tank hose. Soon after, the canister. As a final recourse, see if there’s an electrical malfunction.

Every time you fix something, grab your scan tool and check for the error again. Keep going if the error persists.

Worn out cap

Alright, first things first. The gas cap. Make sure that your cap is not stuck, worn out, or has any sort of issues whatsoever.

If you find it to be stuck, well, unstuck it somehow. If you notice the cap is giving you trouble because it’s worn out, it’s time to replace it.

Faulty hose

Look for your fuel tank and check the hose that connects it to the EVAP system.

Similar to what I’ve explained above, what you have to do is simple: if the hose is loose, attach it. If it’s worn out or defective, replace it. If it’s okay, read down below.

Clogged canister

Time to check the charcoal canister. If you never tried this before, let me assure you, it’s incredibly easy to do.

All you have to do is shake your canister a little bit. If nothing happens, you’re good to go. If something falls off the canister (water, fuel, pieces of the canister), you need to replace it.

Malfunctioning wires or sensors

As a last resort, check the wires, sensors, and fuses related to the fuel tank.

You may be getting a bad reading because something electrical went wrong and not because something is wrong with your fuel tank.

Other than that, it’s time to call a mechanic!
