    I recently got a code P0251 which translates into a problem with the injector pump metering control, according to the technician who checked it, which he said is probably caused by the modulator piston displacement sensor. Would someone please explain this to me and tell me where this faulty sensor is located and the proceedure to replace it. Thankyou, Dean
