Chevy Truck/SUV Fuel Tank Pressure Sensor Replacement (P0446 Fix)

Here is how I fixed the P0446 trouble code on my 2007 Chevy Suburban by replacing the fuel tank pressure sensor. This should be similar for the Chevy Silverado, Avalanche, Tahoe and Suburban as well as the GMC sierra, Yukon, Yukon XL and Cadillac Escalade.

Good job dude, looked like a fun job, ha ha. I've been fixing my own vehicles for year's. I'm not going to pay a mechanic $100. plus an hour to fix something I can do myself. The money you save, can buy a lot of tools. I know most of the time the jobs turn out to be a pain in the ass, but it gives you a good feeling of accomplishment and you save a bundle! It's a win-win!

You’re not a mechanic, but you are my hero

[@tomg962]

Great video, I am having a similar problem with a truck and this was helpful.

[@kitevski3923]

You're a better mechanic than you think

[@SevenFortyOne]

Thanks! I still have to put in a disclaimer. I have huge respect for anyone who does this type of work on a daily basis.

The physical shape that I am in I have to take it to our dealer but he is really fair on labor. I know it is a different story close to the cities for us. Good job! Yep feeling around without seeing what you are doing is fun. But your camera is doing a good job telling you what you did.

My 09 silverado 5.3 is throwing a p0446 but everything else on the internet says that's EVAP. She has been stalling on me lately. Any help would be appreciated

[@tpcdude]

What video did you review LI battery?

[@user-yg4pi6fm5d]

What is the scan tool you use? I looked in your Amazon store & didn't see one.

[@SevenFortyOne]

I got it at harbor freight...I think it's a Zurich

[@user-yg4pi6fm5d]

Thank you I appreciate it

[@vincechidester5380]

How did you know it was the fuel tank pressure sensor and not the vapor canister purge valve or gas cap evap?

[@SevenFortyOne]

I checked the gas cap first and it was fine. I then changed the canister and still got the code. If you have access to a smoke machine you can check the canister without removing or replacing it.
