P027B - FUEL PUMP MODULE B CONTROL CIRCUIT RANGE/PERFORMANCE
| Description: | The fuel pump control module 2 monitors the duty cycle and frequency of the signal it receives from the PCM. The fuel pump control module 2 determines if the signal from the PCM on the 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 FPM2 circuit to report the concern to the PCM. This DTC sets 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. | ||
