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.
