DTC DESCRIPTION P0627 - FUEL PUMP A CONTROL CIRCUIT/OPEN
| Description: The fuel pump control module monitors the fuel pump module and secondary circuits for a concern. If the fuel pump control module detects a concern with the fuel pump module or secondary circuits, the fuel pump control module sends an 80% duty cycle signal on the fuel pump monitor (FPM) circuit to report the concern to the PCM. This DTC sets when the fuel pump control module is still reporting a concern with the fuel pump module or secondary circuits after a calibrated amount of time. | |||
