2004 Chevrolet Tahoe LS 5.3L MIL Lamp on
Posted to GM Driveability on 5/28/2008 4 Replies

This vehicle came about a month ago with MIL on & wouldn't go over 15 mph. Found PCM was in "reduced power mode" & codes P0120, P0220, & P1516. Checked scan data, all looked good so we cleared codes & couldn't get them to come back.

Truck came back in 3 days ...
