Injection Pump Metering Control

Diagnostic & Technical Explanation
Code P0251 (Injection Pump Fuel Metering Control A (Cam/Rotor/Injector)) sets when the ECM detects an open circuit, out-of-range response, or performance fault while controlling a rotary/distributor injection pump's internal metering solenoid. Causes are a failed metering solenoid, internal pump wear, or damaged control wiring.

These 26 diagnostic trouble codes share one detection mechanism and one repair path, which is why MechanicDB groups them into a single authored fault family rather than repeating the same explanation 26 times.
