Check engine light came on.
Pulled the OBDII codes and it was showing P0452 which means the Fuel Tank Pressure Sensor is bad.
It could be a faulty gas cap seal or a bad harness wire as well, but my gas cap was fine, and a bad wire is unlikely, so I just replaced the sensor.

Steps
1. Wait until low fuel light comes on so tank is almost empty
2. Take off fuel tank straps, but use something to support the back end. I used a small cardboard box.
3. Reach up and over the tank, unclip the sensor hardness, then pull the sensor up and out. It's just compression fit.
4. Push the new sensor in place, being careful not to knock debris into the hole.
5. Reattach wire harness.
6. Tighten tank straps back up.
7. Clear OBDII code, fill with a few gallons, and test drive to ensure the code doesn't come back on.

Great video! Thank you, very helpful!
Thanks for posting this brother!
I love the part where he is looking for the "spot"! Reminds me of high school all over again. Thanks for the vid man. Helped a lot.
Nice angle with the camera. Helpful and quick fix, when I do mine I will stick a vacuum up there, looks like you knocked some of that dirt in your hole.
I definitely should have done that as well🤙🤙🤙
Excellent dude! I’m doing this! Thank you!
Thank you for this video just got a 02 gmc sierra denali 1500 quadrasteer and got this code this was super helpful so thank you again
Good video. Thanks for sharing.
Thank you very much. It was real help
Good job
Thanks for the video and camera position
What happens if you don't change sensor?
I'm laughing and thinking it needs some hair around it but I've been there. good job
My high school boss used to say the same thing all the time. 🤣🤣🤣
Thank you
After watching this video, I went and got a new sensor for my own 09 1500 5.3L extended cab. I used my phone to take some pictures above the gas tank so i could see where the sensor was at and saw that two of the wires on the cable that plugs into the sensor itself had been chewed my mice. Wasted 93 bucks on a new sensor because the only one they had in store was the most expensive (of course) and now gotta return it. The truck had been sitting in my grandpa's driveway for about two years, probably only being driven once or twice. I got the truck after he passed, and in that time, mice had found their way into a small area next to the fuel tank and apparently thought those two wires were in the way. Super annoying.
That could be my problem too! Hope not.
@@andydugan1911 what I ended up doing was parking on some oil change ramps and my brother soldered them lol. Probably not a permanent fix but so far has held for over 2 months of winter and salty roads
Going through evap hell myself now with my 09 LS Silverado 1500 rust bucket. It’s rotting out from under me. May not pass next inspection. Shock mounts rotted and bed rails underneath one is gone. Rear cross member near bumper almost all gone. Sad. Replaced the vent solenoid and light was off for three days then came back on with same code and this 452. Gas gauge broken as well. I’ve had it.
Great video,Thanks.
Glad it was helpful!
Awseome, thank you for sharing.
Glad you enjoyed it
Fixed my truck
Ur good.....no cussin
Great....i going to clean with air pressure first the tank to remove some dust first...to prevent dirt going into my gas tank
Definitely should have done that myself🤙🤙🤙
Before you pulled the sensor out you should of had blow away all the dirt and crap from the top of the tank so you don't end up plugging the new one with all that junk.
👍👍
I was able to do it without lowering straps or anything.
Yes knock all the dirt in😈🤌🏼
Did you smell a lot of fumes from your gas cap?
I did not
Put some hair around it there bud you’ll find it every time good video 👍
What year is this truck in this video?
On 2011 it’s different I think it’s inside the tank
It's a 2001
I thought code p0451 was for the fuel pressure sensor
Both p0451 and p0452 are related to the EVAP system
@@naec7and apparently 0446
And p0454
Only reason i wont like this is cause your likes are currently at “665” and ill be damned if im apart of the problem 😂😂
Why not just approximate Location cut a small hole in the truck bed going through the top, replacing the part and then just patch the hole you cut? Too lazy maybe?
