Injection Pump Fuel Metering Control F Range/Performance (Cam/Rotor/Injector)
This code is in our catalogue but has not yet been through editorial review, so the guidance below is limited to what our structured data supports. We publish deeper diagnostic content only after a code has been reviewed — here is why.
Fuel metering on channel F of the injection pump is outside the calibrated tolerance. Mechanical wear or pressure regulator drift.
A trouble code records what a control module measured. It does not identify which part failed. Test before replacing anything.
