The Alfa-Romeo Code P0265 is one of the most common problems when diagnosing and repairing a car. This code indicates that the Cylinder 2 Injector Circuit is high. A car’s performance and fuel efficiency are determined by the Powertrain Control Module (PCM), which controls the injectors’ operation. The PCM will calculate the appropriate amount of fuel to be injected based on engine operating parameters such as engine and ambient temperature, engine speed and workload, and exhaust gas composition. However, if any of the components related to the injectors are damaged or malfunctioning, the Alfa-Romeo Code P0265 will be triggered.
