Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information ECM-P019300

Condition




The Engine control module (ECM) monitors the fuel pressure in the fuel rail using the fuel pressure sensor.
The diagnostic trouble code (DTC) is stored if the Engine Control Module (ECM) detects that the signal from the fuel pressure sensor is too high.
The diagnostic trouble code can be diagnosed when the ignition is on.

Substitute value
- The fuel pressure is set to a constant.
- The control signal to the fuel pump (FP) control module is set to a calculated value.

Possible source
- The signal cable is short-circuited to voltage.
- Open-circuit in the signal cable.
- Damaged fuel pressure sensor.

Fault symptom[s]
- Malfunction indicator light (MIL), on
- Engine misfires.
