P025B - FUEL PUMP MODULE CONTROL CIRCUIT RANGE/PERFORMANCE
| Description: | The fuel pump control module monitors the duty cycle and frequency of the signal it receives from the powertrain control module (PCM). The fuel pump control module 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 sends a 20% duty cycle signal on the fuel pump monitor (FPM) circuit to report the concern to the PCM. The test fails when the fuel pump control module is still reporting that it is receiving an invalid duty cycle or frequency from the PCM after a calibrated amount of time. | ||
