Code P0265 2015 Chevrolet Silverado Description

The P0265 code on a 2015 Chevrolet Silverado indicates that there is a high voltage condition in the control circuit of the fuel injector for cylinder 2. This means that the Engine Control Module (ECM) has detected that the voltage in the circuit is higher than the specified range. The fuel injector is responsible for delivering the precise amount of fuel into the combustion chamber at the right time.
