Injection Pump Fuel Metering Control “A” Range/Performance (Cam/Rotor/Injector)

What the P0252 code means

P0252 is an OBD-II generic code for the injection pump fuel metering control valve circuit when the engine control module (ECM) did not receive a signal from the valve indicating movement.

What causes the P0252 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 the current is out of specifications, then it sets the code P0252 and turns on the Check Engine Light.

What are the symptoms of the P0252 code?

  • The Check Engine Light will be illuminated and the code is set in 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.

How does a mechanic diagnose the P0252 code?

  • Scans codes and documents the code in the ECM

  • Diagnose code as per the manufacturer's pinpoint test to verify the fuel injection pump failure

  • One manufacturer suggests to clear codes, and if the code returns, to replace the injection pump.

Common mistakes when diagnosing the P0252 code

  • Clearing ECM memory codes before checking the freeze frame data of the failure
  • Failing to clear ECM codes after the P0252 codes are fixed and retesting the system

How serious is the P0252 code?

Code P0252 is an indication that the fuel injection pump cannot control fuel into the engine and must be replaced to fix the code and drive symptoms.

What repairs can fix the P0252 code?

Additional comments for consideration regarding the P0252 code

Code P0252 is generated by a diesel engine vehicle that has an injection pump that cannot control the amount of fuel injected into the cylinders and will cause the code to set. Some vehicles may have a fuel valve that can be replaced without replacing the entire fuel injection pump. Follow the manufacturer pinpoint tests for diagnosis and repair for your vehicle.
