P0180 FPT SENSOR

Description

INFOID:0000000000955026

Fuel pump temperature sensor is built in the fuel pump. The sensor detects the fuel temperature in the fuel
pump and calibrates the fuel injection amount change by fuel temperature.

P0190 FRP SENSOR

Description

INFOID:0000000001089064

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-1393, "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:0000000001089062

1.

CHECK GROUND CONNECTIONS

1.

Turn ignition switch OFF.

2.

Check ground connection E17. Refer to Ground inspection in

GI-41, "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
