2009 Chevrolet Silverado 1500 LT 5.3L MIL Lamp on
Posted to GM Driveability on 8/27/2013 14 Replies

This one came in with the check engine light on. P0521 - we went through the ppt and decided to replace the oil pressure sensor. The light came back on a few days later. I do NOT believe there is an engine oil pressure issue. Thanks, Mike
