2010 SEL, codes P0451 and P1450

[Chevy Guy]

Just wanted to share this in case it might help someone. 

 

My 2010 SEL started throwing a P0451 code a while back. Resetting would fix things for a couple days but it would always come back, sometimes with a P1450 code. Changed the Canister Vent Valve... nothing. Changed the Purge Solenoid... nothing. Finally gave in and swapped out the Fuel Tank Pressure Sensor Assembly... bingo! The valve and the solenoid were $60 each from Napa so I had taken the chance before spending $250 at the dealer on a new FTPS. Hey, I had to try, right? Anyway, it's been a month and the car is still working fine (knock on wood) and I have a few spare parts on my garage shelf. All good.

Hey, I see your post was from 6 years ago, but I have the same vehicle with the same codes. The dealership told me either 1) fuel tank pressure sensor 2) charcoal canister.

I did what you did and replaced the Canister Vent Valve, nothing. I was going to change the Purge Solenoid but the dealer said that was operating properly. I already have the Fuel Tank Pressure Sensor assembly and was going to try and install it. I am pretty good at working on my own cars but this might be just out of my capability. Did you change it yourself or get a mechanic to do it?
Thank you !

Hi Brando. The OP (ChevyGuy) has not signed in for ~2 1/2 years, so you may not get a reply. Hopefully one of our tech members or another member familiar with this job will see this and jump in to help.

 

Keep us updated and good luck.

Brando,  I also have the P0451 code on my 2012 Fusion. I have been looking for the location of the "Fuel Tank Pressure Sensor Assembly" and the part number.  Can't find anything in the forums or the part dealer sites.  Would appreciate any help you could give me!

 

Thanks

Hello. I actually changed my FTPS assembly 2 days ago. It was very hard but got it done. I also changed the charcoal canister and my engine light went off today, yay!

part number is AE5Z-9A228-B. I don’t have a picture of all the connections but I’ll attach a picture of the sensor which is part of the assembly. It’s below the car. Towards the back of the car, above the rear sub frame (where the rear axle would be if it had one)

Hi, thanks for the picture and part number!  I was afraid it might be located above the gas tank.  Been looking everywhere for this part and location.  I have ordered the Charcoal Canister and will replace it first. Last winter I drove over a curb in a parking lot and may have cracked the canister.  They are not protected very well under the spare tire.  So thanks again, now I have a direction to go in!
