DTC DETECTION LOGIC

DTC		M.U.T.-III SE screen terms (Trouble diagnosis content)	DTC detection condition
P119C	00	FUEL PRESSURE SENSOR (Fuel pressure sensor)	Diagnosis condition	Battery voltage: 8 V or more Engine speed: 600 rpm or more Engine coolant temperature: With a background of 65°C (149°F) or more during the trip Remaining fuel amount: 15% or more Fuel cut: No
			Signal (terminal)	Fuel rail pressure sensor signal
			Threshold	Fuel rail pressure between MAX and MIN differs more than 0.1 MPa (1.02 kg/cm², 14.5 psi)
			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 P119C is displayed with DTC P0192, P0193 or P06B0, first perform the trouble diagnosis for DTC P0192, P0193 or P06B0.

Is applicable DTC detected?

Perform diagnosis of applicable.

DTC: P0192 Refer to DTC Description.
DTC: P0193 Refer to DTC Description.
DTC: P06B0 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.
Remaining fuel amount must be 15% or more.

3.PERFORM DTC CONFIRMATION PROCEDURE

Start the engine and warm it up until the engine coolant temperature reaches 70°C (158°F) or more.
Drive the vehicle and accelerate 10 consecutive seconds or more with the engine speed 1,500 rpm or more.
Check “Self-diagnostic result” of “ENGINE”.

Is the DTC detected?
