P027B - FUEL PUMP MODULE CONTROL CIRCUIT RANGE/PERFORMANCE
| Description: | The fuel pump control module 2 monitors the duty cycle and frequency of the signal it receives from the powertrain control module (PCM). The fuel pump control module 2 determines if the signal from the PCM on the fuel pump command (FPC) circuit is a valid duty cycle and frequency. If the duty cycle or frequency is invalid, the fuel pump control module 2 sends a 20% 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 that it is receiving an invalid duty cycle or frequency from the PCM after a calibrated amount of time. | ||
