DTC Fault Trigger Conditions
DTC Description Fault Trigger Condition PCM P025A:00 Fuel Pump Module "A" Control Circuit/Open: No Sub Type Information This DTC sets when the PCM detects the FPC circuit is open or shorted to voltage or ground. PCM P025B:00 Fuel Pump Module "A" Control Circuit Range/Performance: No Sub Type Information This DTC sets 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. PCM P025C:00 Fuel Pump Module "A" Control Circuit Low: No Sub Type Information This DTC sets when the PCM detects the FPC circuit is shorted to ground. PCM P025D:00 Fuel Pump Module "A" Control Circuit High: No Sub Type Information This DTC sets when the PCM detects the FPC circuit is open or shorted to voltage. PCM P027B:00 Fuel Pump Module "B" Control Circuit Range/Performance: No Sub Type Information 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.
