Kubota P0265 – Engine Control Module (ECM / ECU): Injector Driver #2 Short-To-Power

This code indicates a high-voltage short circuit in the control circuit for the cylinder #2 fuel injector. The system detects that the voltage between the injector and the control module is abnormally high, or that the injector coil has shorted internally.

1. 1

   Inspect the wiring harness between the ECM and the #2 fuel injector for open circuits, shorts, or physical damage (chafing against engine components)

2. 2

   Ensure the electrical connector at the #2 injector is securely fastened and free of corrosion or fluid intrusion

3. 3

   Use a multimeter to test the internal resistance of the #2 fuel injector coil (a reading outside OEM specifications indicates an internal short)

4. 4

   With the key on, check the voltage on the injector driver circuit to verify if it is shorted to a power source (battery voltage)

1. 1

   Disconnect Power

   Disconnect the negative battery cable to prevent electrical spikes.

2. 2

   Isolate the Fault

   If the wiring harness tested faulty during diagnostics, repair the shorted wire or replace the injector harness section.

3. 3

   Replace the Injector

   If the wiring is intact and the injector coil is internally shorted (the most common cause for P0265), remove the fuel lines and retaining brackets for cylinder #2.

4. 4

   Install New Injector

   Install the replacement fuel injector with new O-rings and copper sealing washers. Torque the hold-down clamp and fuel lines to OEM specifications.

5. 5

   Reassemble and Bleed

   Reconnect the electrical connector. Reconnect the battery. Prime the fuel system to remove air.

6. 6

   Clear Codes

   Use a diagnostic scan tool to clear the P0265 code from the ECM. (Note: Depending on the engine model, you may need to program the new injector's QR compensation code into the ECM using a Kubota diagnostic tool).
