29 thoughts on “How to Replace Fuel Tank Pressure Sensor 00-06 Chevy Suburban

  1. Using a screwdriver to get it out broke two pressure sensors for me.. Had to shove the stem down into the tank to clear the hole. I would suggest a different tool but not sure how to pull vertically with just an arm's space. This was for a 2001 silverado 1500 without dropping the tank, I am skinny enough to prop myself between the body and the frame, put a small light up just to see what I was going for.

  2. This may seem like a silly question, but you didn't mention whether it was necessary to completely drain the fuel tank before attempting this repair or if it is okay to leave a small amount of fuel; such that it won't spill out when disconnecting the two fuel lines? Thanks. I have a 2001 Tahoe. Love your videos!

  3. When this part is bad does it throw a trouble code. Also, does it cause hard filling at the pump. I already replaced the Evap. Vent Solenoid.

  4. What if the nub of the old sensor breaks off and falls in the hole where your supposed to put the replacement sensor?

  5. Check Engine light came on. When to Autozone. it showed it was the Fuel Pressure Sensor. Thanks to this vid I was able replace it. Didnt have to drop tank. i was able to reach it. Did it on 03 Chevy Z71 with installed Leveling kit. Had room to manver.

  6. Highly recommend draining fuel tank or running it to empty. Replaced the fuel pressure sensor on 2001 Chevy Suburban with about 12 gallons of gas in tank. Lowered back of tank to a tilt of about 30 degrees. Nothing came out until I popped the pressure sensor off and then there was some type of vacuum release and the gas came pouring out. Had to let it evaporate before continuing work. Lost as much gas as I spent on the pressure sensor. Lesson learned.

    Also, on my Suburban there was a metal cover with two 10mm nuts that had to come off before I could get to the pressure sensor. That cover seems to be missing in the video and adds a couple of steps to the process and makes access even more important.

  7. Why not lower the spare tire to make it easier accessible? And use a battery powered impact to remove bolts for straps?
    Auto mechanics work on time. Do it yourselfers think about that. The video is very helpful.

  8. My truck wont start on the first try it takes a couple cranks to start. I think it loosing fuel pressure. Dont know if i should just change the fuel tank pressure sensor. Or change the whole fuel pump with it. Please?

  9. Im about to do this on my 2004 Escalade esv. The old P0446 wont go away. Replaced vent solenoid, purge valve, fuel cap and canister. I hope the tank is not too heavy because im doing this all by myself with jack and jackstands. Low fuel light just came on so thats a plus. Wish me luck.

  10. Be prepared for the gas tank strap closest to the spare tire not to come off. Tried for an hour. The bolt just kept spinning and wouldn't release. Had to run it up to a shop. Oh well.
