DTC Descriptors



DTC P0641



- 5 V Reference Circuit



DTC P06A6



- 5 V Reference Performance



Diagnostic Fault Information



Circuit/System Description



The fuel pressure sensor is located on the fuel line. The fuel pressure sensor monitors the fuel pressure in the fuel line. The fuel pump control



module monitors the voltage signal from the fuel pressure sensor.



Conditions for Running the DTC



The ignition is ON.



Conditions for Setting the DTC



The fuel pump control module detects that the fuel pressure 5 V reference is above or below a predetermined voltage threshold.



Action Taken When the DTC Sets



DTCs P0641 and P06A6 are Type A DTCs.



Conditions for Clearing the DTC



DTCs P0641 and P06A6 are Type A DTCs.



Diagnostic Aids
