I have a 2012 Silverado, 5.3L V8, that the check engine light is on (solid).
All fluids are good, temp is good and the motor sounds good,, anyone else have issues with the oil pressure Sensor? The code I got from the guy at Autozone is P0521,,,,, anyone else have this problem?
There was a GM service bulletin on this issue, but not for the year of your truck. It's possible the problem has carried over to the following production years. Check this link for a write up and a link to the bulletin: http://engine-codes.com/p0521_chevrolet.html
I bought a used 2012 Chevy 1500 two months ago with the same problem and code. The sensor has difficulty reading the gauge but is not a major issue. Replaced sensor and problem goes away. It's a computer issue that isn't major
