P0190 FRP SENSOR

P0190 FRP SENSOR

Description

INFOID:0000000001162592

The fuel rail pressure (FRP) sensor is placed to the fuel rail. It measures the fuel pressure in the fuel rail. The
sensor sends voltage signal to the ECM. As the pressure increases, the voltage rises.The ECM controls the
fuel pressure in the fuel rail. The ECM uses the signal from fuel rail pressure sensor as a feedback signal.

DTC DETECTION LOGIC

NOTE:
• If DTC P0190 is displayed with DTC P0641, first perform trouble diagnosis for DTC P0641. Refer to

EC-1180, "DTC Logic"

.

• Conditions for applying the diagnostic procedure to the stored DTCs:
- The DTC is declared present after the ignition is switched on when the engine is running outside idle speed.
• If the DTC is present:
- Malfunction indicator (Red) lights up.

Diagnosis Procedure

INFOID:0000000001162594

1.

CHECK GROUND CONNECTIONS

1.

Turn ignition switch OFF.

2.

 Check ground connection E15. Refer to Ground inspection in 

GI-58, "Circuit Inspection"

.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Repair or replace ground connection.

2.

CHECK FUEL RAIL PRESSURE SENSOR POWER SUPPLY CIRCUIT

1.

Disconnect fuel rail pressure sensor harness connector.

2.

Turn ignition switch ON.

3.

Check the voltage between fuel rail pressure sensor connector and ground.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Repair open circuit or short to ground or short to power in harness or connectors.

3.

CHECK FUEL RAIL PRESSURE SENSOR GROUND CIRCUIT FOR OPEN AND SHORT

1.

Turn ignition switch OFF.

2.

Disconnect ECM harness connector.

3.

Check the continuity between fuel rail pressure sensor harness connector and ECM harness connector.

DTC No.

6.

CHECK INTERMITTENT INCIDENT

Refer to 

GI-55, "Intermittent Incident"

.

>> INSPECTION END

Component Inspection

INFOID:0000000001162595

1.

CHECK FUEL RAIL PRESSURE SENSOR

1.

Turn ignition switch OFF and wait at least 1 minutes.

2.

Reconnect harness connector disconnected.

3.

Turn ignition switch ON.

4.

Select “DATA MONITOR” mode with CONSULT-III.

5.

Check that the “RAIL PRESSURE” indication. 

If the value is lower than 30 bar? 

YES

>> INSPECTION END.

NO

>> Replace fuel rail pressure sensor.
