Code P0265 BMW Description

This fault code is stored in the Engine Control Module (ECM) when the injector control circuit does not behave as expected. The ECM uses the induced voltage from the injector to indicate that the fuel injector circuit is operating correctly electrically. It does not signal the mechanical condition of the injector. When the ECM opens the ground circuit for an injector, to cease current flow, a voltage is induced into the winding. This voltage shows the electrical integrity of the injector and associated wiring. Absence of this induced voltage results in a fault code being stored in the ECM.
