How is fault code P0265 fixed?

A typical diagnostic sequence used by mechanics, provided here for educational reference only. Diagnostic work should be performed by a qualified mechanic with the appropriate tools and training. 1. Pull the connector off the cylinder 2 injector and have a proper look. Check for green corrosion on the pins, pushed-back terminals, water sitting in the plug, or a cracked connector body. A surprising number of these are fixed right here 2. Measure the injector coil resistance across the terminals with a multimeter. On most petrol injectors you're looking for roughly 12 to 16 ohms; well outside that range and the injector is suspect. Diesel injectors read differently, so check the spec for your engine 3. Back-probe the control wire with the engine cranking and confirm you're seeing a pulsed signal, not a steady high voltage. A constant high reading tells you the circuit isn't being switched as it should 4. Inspect the harness from the connector back towards the ECM for rubbed-through insulation, melted sections near hot exhaust parts, or any sign of a chafe point 5. Swap the cylinder 2 injector with one from another cylinder and clear the code. If the fault follows the injector to the
