P2A1F indicates that the engine control module (ECM) has detected an out-of-range or performance fault in the fuel metering control circuit for injection pump circuit F, which is associated with the cam, rotor, or injector. The ECM monitors the expected fuel quantity or timing command versus actual response and sets this code when the signal or actuator performance falls outside programmed limits.
