P0453 MYSTERY Part or fix question 2005 Expedition

[Monster63]

I was able to find what is being called a used 2005 2006 ford expedition gas tank on ebay.
crazy that I was only able to find a good pic on ebay but it is what it is.

is this the part that needs to be replaced to solve the p0453 code issue?
Does that part connect to those lines OR is it part of the lines and they need to be replaced also.

Any help direction or more pics is greatly appreciated

I could be wrong but I think the fuel tank pressure sensor is in a hose going to the tank visible by lowering the spare tire and looking up at the hoses. I don't recall ever seeing the doohickey Circled in your picture. And I removed the tank twice now.

Briangee

Thank you. Can you point out where this part is from this pic?

 

[BRIANGEE]

No, you'll have to get that spare tire out of the way and follow the hoses that go out of the rear of the tank up towards your fuel filler neck and canister. I recall seeing a pressure sensor spliced into the line around that area - you'll know you found it when you see the electrical connector going to the fuel line. If I can find some time here I'll try to post something more.

 

[BRIANGEE]

Here's what it looks like if you live in a cartoon. IIRC you don't have to remove the tank to get to this as the instructions state.

Thank you very much BrianGee

Unfortunately after 45 minutes under the suv tracing the fuel line from the filler neck down to tank and every other hose in between, on my 2005 I dont see anything that looks like that diagram. The only thing I saw that was even "disconnectable" was a hose that went to what I am assuming is the evap canister contraption. And it had the typical ford connection with the green press tab to release it. There was a wired connection in that evap canister contraption vicinity ( not even close to a fuel line ) that connected to something but definitely didnt fit the description of fuel sensor.

I am beginning to suspect in 2005 and 2006 ford did something different.
I dont have an issue dropping the tank but I really need to have this MYSTERY part on hand so I can get it done in a timely manner.
In your pic it seems as if the part is mounted inline, i havent seen a part yet that I have googled which resembles an inline part. Everything I have seen has been a fuel rail switch or a twist on top of tank part both having an electrical connection.

Thanks again and if you have any other tips please let me know.

Have you stuck an inspection mirror above the tank and looked? I'd hate to have sent you on a wild goose chase - it's possible Ford changed it for 2005. The diagram I posted is good up to 2004 for sure. If it is in the same location though you might have to at least lower the tank a bit to get to it. Of course, you'd want to take a loof with a mirror first.

 

[BRIANGEE]

There must be two variants because even when I search my year of expy' an inline pressure sensor is not shown yet that's what I've seen and the installation diagram shows it. So I think you're absolutely right in the picture you posted after having looked at the actual part online.

 

[Monster63]

I am gonna try to get it on a lift and try to see anything with a mirror or even a scope if my buddy has one.
This entire thing has completely blown my mind lol. Like you mentioned every diagram or schematic doesnt really provide alot of solid info for 2005. Even when you search the part on rockauto.com it comes back as the fuel rail part. You have to search fuel tank pressure transducer sensor to get a part that looks remotely close to the one on the tank I posted and even then the transducer part isnt an inline part. It twists into the fuel tank and has a wiring harness. No fuel passes thru it.
Thanks again and if you find anything new please post.

 

[Monster63]

Havent been able to get it on a lift. Canr really see anything even with a mirror under it. Seems like there is a plastic cover over that side of the tank. Probably cause the fuel lines are on that side.
Can anyone else shed some light on this particular 2005 gas tank view.
Thanks

I looked at an 06 service manual on it. This is what I see. #8

 

[Monster63]

Thank you for the pic.
I am still unsure of what is going on.
#8 says its an electrical connector but not actually a part number or part name?
It does however show it connecting to the part in my pic of the actual top of tank.
Any chance that service manual gives a part number for what it plugs in to?
Thanks

 

[sscharlie]

Try this for research.
I haven't actually found a good picture of it besides the first one I posted.

 

[Monster63]

Definitely getting closer.
I am finding 3 different parts with 9C052 in the part number though. I think am gonna have to just drop the tank and see which one I have.

Hey man, you have any resolution with this?

I'm fighting it now, generally stick to older cars... all this plastic is tearing up my arms.

I have dropped my tank and searched and searched for what most parts stores show as the Fuel Tank Pressure Sensor. I found a part that looks like one of the pictures above. Just wondering if you've dove any further into it.

Just an FYI for anyone in the future. I took my 05' to a stealership and they said the fuel take pressure sensor is shot, said almost $1000 to replace. The sensor is pictured above, it's the first one, it's inline on the hoses for the EVAP system. Ford does not view that sensor as a replaceable component - hence they don't sell just that sensor - they want you to replace the entire hose system. Part # 5L1Z9C015AA. At the time of me posting this there is one guy on eBay selling just the sensor "new" - not in original packaging. I'm likely going to opt and spend the extra $ and buy the entire hose system vs risking the time/work to replace just the sensor and it not being correct.

Good luck to anyone in the future.

ALSO - FYI. This cannot be accessed without dropping the tank. It's about halfway across the tank on the top towards the passenger side. It's all but covered by the heat shield. There are two hoses running together from front to back, its on one of them.

I never had a chance to get that far yet. Thank you for the update. Of course it is bad news for the both of us. Not sure if you will see this before you work on it but can you possibly get pics of what you have to do to and the actual part you replace. Was the part available at retail stores or is ford the only one that sells the complete assembly. Again thanks for the update. I really appreciate this info.
Oh, 1 other question. What exactly happened to cause yours to go bad? Did it short out?

I haven't done the work yet. No one seems to actually have the part in stock. I ordered it from on ebay ford parts dealer. Prob wont have it til next week. I'll try to snap what pics I can - difficult to do under the car.

No clue what caused it to go bad. The dealership said they just go out, I imagine the sensor has just gotten plugged up with gunk or something along those lines (car has +200k miles. I spent a week in the mountains on some very dusty and dirty roads right before this happened - not sure if that has anything to do with it or not.

It's my daily (other car is a 66 galaxie) and the tags are two months expired due to failing emissions, so I am very motivated to get this resolved. I'll try to post back with results.

Ok thank you. I think I mistakenly shorted mine out when I put a 20 amp fuse in the F1.34 slot instead of the F1.35 slot when replacing what I thought was a blown fog light fuse in slot F1.35
When I turned the key it stuttered and ******. Never had that happen before. I turned the key back to off and then tried to start again. This time it started and immediately threw that P0453 code. Now after looking into my mistake in the fuse box I remedied the blown fog light fuse BUT if I take that 20 amp fuse out of F1.34 the suv will not start. By that I mean turn key to on and nothing, no cranking at all. Everything acts like it is supposed to start ( lights on, radio, dash lights up ) but it does nothing without that fuse in there now.
To make it even more nonsensical, when i put the fuse back in and start it, I can pull the fuse while running and the suv still runs. Turn it off and try again, no go.

F1.34 doesnt reference anything about emissions. It does mention the PCM though. So I think I may have shorted the wiring or connection from that part that communicates with the PCM when I gave it power from the 20 amp fuse.

Bananas right. I dont even use the fog lights lol. I was just surprised they didnt come on when I tried them one day and here I am now with this absurd emissions code that Ford requires you to drop an entire gas tank to hopefully remedy. And probably like you, I had to search Google for hrs just to even find something about this part. Even the helpful guys that posted technical pics it still wasnt specific in the diagrams. And the fact that 3 parts have the same part number in them even made this more of a headache.
Cant wait to hear how yours turned out.
BTW, I had just passed emissions test 3 weeks before this incident. So I got lucky in a way until next July cause it really isnt causing me any mechanical issues. Just a CEL.

 

[Monster63]

Another question if you can,
When you get the part can you please post what color wires come from your onboard plug that plugs into the plug of the part you bought. After typing that long message earlier I am wondering if maybe I shorted or fried the wire from the onboard harness that goes to the pcm.
Thanks again
