The fuel injection system is responsible for adding fuel to the engine cylinders. The amount of fuel and the timing of the fuel injections are vitally important for successful combustion of the air and fuel mixture to take place. Then your engine can generate enough power to satisfy your acceleration demands.
The powertrain control module controls the fuel injection system with the help of special transistors known as drivers. When the powertrain control module receives information from various sensors of the vehicle, it knows how much fuel to have added to the engine cylinders. The drivers are responsible for activating and deactivating the fuel injectors of the fuel injection system.
If you ever experience a weak engine performance or low fuel efficiency because of increased fuel consumption, then a problem may exist within your fuel injection system. Run a diagnostic scan on the powertrain control module. If trouble code P0265 comes up on the screen, then it means the Cylinder 2 Injector is not functioning properly because of a circuit related issue.
The causes of trouble code P0265 may include a writing problem, bad fuel injector, bad fuel injection control module, or a problem with your powertrain control module. In most cases, you’ll likely have a problem with your fuel injector or fuel injection control module. You can fix the problem by replacing the defective component. Of course, it is a better idea if a professional mechanic replaces the component because it requires a lot of automotive skill to perform this replacement task.
You need to get the problem resolved quickly. If you let your Cylinder 2 fuel injector continue to malfunction, then it could have a negative effect on your spark plug, oxygen sensor, catalytic converter, or a number of other components. It may even hurt your engine if you let the problem go on for too long.

To save yourself a lot of costly repairs, replace the necessary components as soon as you notice a weaker engine performance and a higher gas bill. In the meantime, you won’t be able to drive as fast on the road because of the low power generated by the engine.
