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.

DTC DETECTION LOGIC

NOTE:
• Conditions for applying the diagnostic procedure to the stored DTCs:

 The DTC is declared present after the ignition has been switched on for at least 10 seconds.

Diagnosis Procedure

INFOID:0000000001089060

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 PUMP TEMPERATURE SENSOR SUPPLY CIRCUIT

1.

Disconnect fuel pump temperature sensor harness connector.

2.

Turn ignition switch ON.

3.

Check the voltage between fuel pump temperature 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 PUMP TEMPERATURE SENSOR GROUND CIRCUIT FOR OPEN AND SHORT

1.

Turn ignition switch OFF.

2.

Disconnect ECM harness connector.

3.

Check the continuity between fuel pump temperature sensor harness connector and ECM harness con-
nector.

4.

Also check harness for short to ground and short to power. 

Is the inspection result normal?

YES

>> GO TO 4.

NO

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

DTC No.

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
