Diagnostic Trouble Code (DTC) Information

ECM-P019200 Fuel Rail Pressure Sensor Low Input

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 low.

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 ground.
- Damaged fuel pressure sensor.

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