Three problems related to check engine light on have been reported for the 2009 Chevrolet Silverado. The most recently reported issues are listed below.
Went out to truck to move it and noticed wipers up on windshield, tried to start it and and only check engine light came on , looked under hood to find an electrical burning smell coming from fuse box. Disassembled fuse box to find it was melted and found evidence of combustion, wiring harness connector x2 pin n5 was melted and connector x5 pins g1 h1,2,3,4 k 4,5,6 and j 2,3,4 had melted this is all the damage that I found.
Driving down highway, check engine light pops up, tractions control indicator light, along with digital display saying several things. Such as, engine reduced power, service traction control soon. . . . . . . . . . Pulled over, had a very rough idle. Made it to parts store and have the truck scanned. Turns out it need the throttel positioning sensor needs replaced. Had them clear the code, drove few more miles and all happens again.
At 46,487 miles had to spend $415. 75 to correct engine light coming on. Now door chime comes on at random times when key is not in ignition.
