DTC DETECTION LOGIC

DTC		M.U.T.-III SE screen terms (Trouble diagnosis content)	DTC detection condition
P119B	00	FUEL PRESSURE SENSOR (Fuel pressure sensor)	Diagnosis condition	Battery voltage: 8 V or more Ignition switch: ON (engine stopped) Engine coolant temperature at previous ignition switch OFF: 65°C (149°F) or more Engine coolant temperature: 35°C (65°F) or less Temperature difference between engine coolant and intake air: Less than 6°C (42°F) Fuel system monitor: Excessively LEAN
			Signal (terminal)	Fuel rail pressure sensor signal
			Threshold	Fuel rail pressure is more than 1.5 MPa (15.3 kg/cm², 217 psi) (calculated by ECM)
			Diagnosis delay time	—

POSSIBLE CAUSE

Harness or connectors
- The fuel rail pressure sensor circuit is open or shorted.
- Sensor power supply 1 is shorted.
Fuel rail pressure sensor
Each sensor, connected with sensor power supply 1 circuit

FAIL-SAFE

Engine operating condition in fail-safe mode

Fail safe mode

Vehicle behavior

Traveling control mode

Accelerator angle variation control

ECM controls the accelerator pedal depression speed to make it slower than actual speed. This causes a drop in accelerating performance and encourages the driver to repair malfunction.

note	ECM does not control the accelerator pedal releasing speed.

Combustion control mode

Stratified charge combustion control at starting

No stratified charge combustion at starting (cold start).

DTC Confirmation Procedure

1.CHECK DTC PRIORITY

If DTC P119B is displayed with DTC P06B0, first perform trouble diagnosis for DTC P06B0.

Is applicable DTC detected?

Perform diagnosis of applicable. Refer to DTC Description

2.PRECONDITIONING-1

If DTC Confirmation Procedure is previously conducted, always perform the following procedure before conducting the next test.

Turn ignition switch OFF and wait at least 10 seconds.
Turn ignition switch ON.
Turn ignition switch OFF and wait at least 10 seconds.

TESTING CONDITION:

Before performing the following procedure, check that battery voltage is 9 V or more with ignition switch ON.

3.PRECONDITIONING-2

note

When it is certain that the previous driving is performed with the engine warmed up, the next steps can be performed.
When it is difficult to satisfy the conditions, performing Component Function Check can identify the presence or absence of malfunction in the part/system that may result in a possible cause of this DTC. (Perform DTC Confirmation Procedure as much as possible.)

Start the engine and warm it up until engine coolant temperature reaches 70°C (158°F) or more.
Stop the engine and leave the vehicle in a cool place (soak the engine) until the engine coolant temperature reaches 35°C (95°F) or less.

caution

The difference between air temperature and engine coolant temperature must be 5°C (9°F) or less.
Never turn ignition switch ON during soak the engine.

Are the conditions satisfied?

4.COMPONENT FUNCTION CHECK

Perform Component Function Check. Refer to Component Function CheckComponent Inspection

Is the inspection result normal?

INSPECTION END.

Proceed to DTC Diagnosis Procedure

5.PERFORM DTC CONFIRMATION PROCEDURE-1

With M.U.T.-III SE

Turn ignition switch ON (engine stopped).
Select “COOLANT TEMP/S” and “INT/A TEMP SE” in “DATA MONITOR” mode of “ENGINE” using M.U.T.-III SE.
Check that the indicated value of “COOLANT TEMP/S” is less than 35°C (95°F).
Check that the difference between “INT/A TEMP SE” and “COOLANT TEMP/S” is 5°C (41°F) or less.
Check “Self-diagnostic result” of “ENGINE”.

Is the DTC detected?

Proceed to DTC Diagnosis Procedure

-1 (Conditions satisfied)

-2 (Conditions not satisfied)

6.PERFORM DTC CONFIRMATION PROCEDURE-2

Start the engine (or cranking) at least 1 second.
Check “Self-diagnostic result” of “ENGINE”.

Is the DTC detected?
