Silverado 5.3 liter engine 07-13 fix for code P0521. First check to make sure you are not low on oil. Then check the wires to the sensor. Then replace the sensor and little filter. I bought my sensor with filter from AutoZone for $50. It took about 30 minutes to change it out.

Do you think this is the same process for the 6.0 2008?
How do you get the wire harness off? Thanks
Is the same on a 2500 Sierra hd 6.0
Did mine and check engine light cleared. But, now I have two permanent error codes displayed on my scanner P0521 & P0523! Any ideas why?
I replaced it with zero swivel and disconnected bothpcv lines, anyways my cage still came out
So did you actually need to replace the oil pressure sensor or just the filter.
Great video man. Have to replace this little guy and wasn't sure how to do it. Cheers.
Have a 2008 Chevrolet Tahoe….Although this video rocks and is very informative, it absolutely sucked replacing the sensor on my vehicle, due to the location of the part. As peeps in other videos stated, "It's a blind job."
What else could it be? I replaced mine but it did not fix the issue. I get the issue to go away by blowing air through the orifice where the sensor goes every time I do an oil change. It fixes the issue for about 2 months and then it comes back and my gauge starts reading lower oil pressure.
Is it common to change this out every couple months?
Would this cause a no crank no start?
So my scan tool 2 psi off and 25 idle thanks for any help
I just bought a 2013 from an online dealer with 81K miles. The PO521 code came up on the way home, about 700 miles into a 850 mile drive. The truck runs perfectly. Any suggestions on where I should start? Replacing the sensor and especially the filter seems like the the way to go but any other advice.
Congrats on your success. I went out and bought all the stuff, including the socket. I can't even get the old one off in spite of trimming that heat shield. Can't even touch it climbing in the engine compartment. I've done quite a few repairs using YouTube . Anyway, I called a mechanic. Maybe because I'm 69? LOL
I rather remove intake, is just 10 min to remove it
Hands down the best video for this fix. Last one I watched had the top end of the engine removed.
Would the code cause a loss of power?
Great video, you made it look easy!
Thanks for the video! I was able to do this job in about 30 minutes. 5/16 bolt is definitely the size needed to get that filter out.
