DTC P2632: Fuel Pump B Control Circuit/Open
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. | |||
