DTC P2632: FUEL PUMP B CONTROL CIRCUIT/OPEN
| Description: | The fuel pump control module 2 monitors the fuel pump module and secondary circuits for a concern. If the fuel pump control module 2 detects a concern with the fuel pump module 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 PCM. The test fails when the fuel pump control module 2 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 2 controls the speed of the fuel pump module by supplying a variable voltage to the fuel pump module on the FPPWR circuit. | ||
