Code P0267 Chevrolet Description

The P0267 Chevrolet diagnostic trouble code indicates that there is a low voltage condition in the control circuit of the fuel injector for cylinder 3. In modern fuel-injected engines, each cylinder has its own fuel injector that delivers the precise amount of fuel needed for combustion. The Engine Control Module (ECM) controls the injector's operation by sending a signal through the injector control circuit. When the voltage in this circuit drops below a specified threshold, the ECM will set a trouble code and trigger the Check Engine Light.
