What is the p1175 code for the chevy silverado?

Diagnostic trouble code (DTC) P1175 indicates "Fuel Trim Cylinder Balance Bank 2", and this holds true in the case of the Chevrolet Silverado. There are a number of different things that can set this code, so begin Your diagnosis by inspecting the fuel injectors for clogs, the oxygen sensors for malfunctions, the ignition for any issues, and the mechanical condition of Your engine. The most common cause, quantitatively, is one or more clogged fuel injectors. You can try to use octane boosters or fuel additive to clear out the clogs, and see if the DTC returns. If the fuel system doesn't seem to be the problem, test resistance and voltage at the O2 sensors, which are located on the Silverado's exhaust.
