Code P0262 Description

The P0262 diagnostic trouble code (DTC) indicates that there is a high voltage condition in the control circuit of cylinder 1 injector. This means that the Engine Control Module (ECM) has detected a voltage that is above the specified range for the injector control circuit of the first cylinder. The control circuit is responsible for delivering the correct amount of fuel to the cylinder for combustion. When the voltage is too high, it can lead to an incorrect fuel mixture, affecting the engine's performance and emissions.
