P2632 - FUEL PUMP B CONTROL CIRCUIT/OPEN
| Description: | The fuel pump control module 2 monitors the fuel pump assembly and secondary circuits for a concern. If the fuel pump control module 2 detects a concern with the fuel pump assembly or secondary circuits, the fuel pump control module 2 sends an 80% duty cycle signal on the fuel pump monitor 2 (FPM2) circuit to report the concern to the powertrain control module (PCM). The test fails when the fuel pump control module 2 is still reporting a concern with the fuel pump assembly or secondary circuits after a calibrated amount of time. | ||
| Possible Causes: |

| Diagnostic Aids: | Check for any harness concerns. The fuel pump control module 2 controls the speed of the fuel pump assembly by supplying a variable voltage to the fuel pump assembly on the FPPWR circuit. | ||
