In a 2017 Chevrolet Silverado 1500, when the check engine light is illuminated, it indicates that a potential issue has been detected, ranging from simple to complex. Possible causes include a loose gas cap, fuel injection system malfunction, faulty oxygen sensor, damaged head gasket, or defective spark plugs. It is advisable to drive the truck for a bit to see if the light turns off on its own. If not, the problem must be addressed to clear the warning light. Attempting some basic fixes, such as tightening the gas cap or replacing spark plugs, could potentially resolve the issue before resorting to diagnostic scanning.
