Check Engine Light

P0260 code definition

Injection Pump Fuel Metering Control “B” Intermittent (Cam/Rotor/Injector)

What the P0260 code means

P0260 is an OBD-II generic code that the injection pump fuel metering control valve circuit has intermittent current flow when the engine control module (ECM) commands the fuel enrichment valve to move.

What causes the P0260 code?

  • The engine control module (ECM) monitors the fuel injection pump metering valve position current feedback when commands to control the valve are sent to the valve from the ECM

  • The ECM attempts to move the valve, and if it cannot get the valve to move every time, then it sets the code P0260 and turns on the Check Engine Light.

  • The problem can be due to an intermittent open circuit in the wiring or connector to the injection pump.

  • The fuel injection pump metering valve may have an intermittent valve internal circuit failure.

What are the symptoms of the P0260 code?

  • The Check Engine Light will be illuminated and the code is set in the ECM memory as a fault.

  • The engine may run too lean or too rich depending on the fuel valve failed position.

  • The engine may have reduced engine power and rough running conditions.

  • Since the problem is intermittent, the drive symptoms may be intermittent also. The engine may run fine when the valve is working and run erratic when it has failed to operate.

How does a mechanic diagnose the P0260 code?

  • Scans codes and documents the code in the ECM. Tries to duplicate the intermittent failure by doing wiggle tests and visual inspections

  • Diagnose code as per the manufacturer's pinpoint test to verify the pump voltage supply and circuits are good to prevent replacing a good injection pump

Common mistakes when diagnosing the P0260 code?

  • Clearing ECM memory codes before checking the freeze frame data of the failure
  • Failing to clear ECM codes after the P0260 codes are fixed and retesting the system
  • Failing to verify the intermittent failure before attempting repairs

How serious is the P0260 code?

Code P0260 is an indication that the fuel injection pump cannot control fuel into the engine intermittently, and the failure may be internal or external of the injection pump. The problem would need to be verified in order to find and repair the vehicle’s engine.

What repairs can fix the P0260 code?

  • Replaces the fuel injection pump
  • Clear codes and road tests the vehicle to verify the code does not return
  • Repairs or replaces the battery power supply to the injection pump circuit
  • Repairs wiring or connections for loose or corroded connections

Additional comments for consideration regarding the P0260 code

Code P0260 is generated by a diesel engine vehicle that has an injection pump that cannot control the amount of fuel injected into the cylinders intermittently. The causes range from a simple wire connection being loose to a complete fuel injection pump replacement being needed. This is why it is important to verify the intermittent failure and verify the failure is found before any repairs are attempted.
