DTC 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 powertrain control module (PCM). The test fails 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. | ||
| Possible Causes: |
|
||
| Diagnostic Aids: | Check for any harness concerns. The fuel pump control module controls the speed of the fuel pump module by supplying a variable voltage to the fuel pump module on the FPPWR circuit. | ||
| Application | Key On Engine Off | Key On Engine Running | Continuous Memory |
