2006 Chevrolet Avalanche 1500 Z66 5.3L MIL Lamp on
Posted to GM Driveability on 9/1/2007 12 Replies

I got the MIL lamp on and ran a test with my OBD detector. It came back with a code PO455 Evap Emission Control System Leak (Large). I erased the codes with my detector and now I'm going to see what happens. The MIL lamp is off right now.
