(Trouble diagnosis content)
DTC detection condition
P119B00FUEL 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
ThresholdFuel 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 modeVehicle behavior
Traveling control modeAccelerator angle variation controlECM 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.
noteECM does not control the accelerator pedal releasing speed.
Combustion control modeStratified charge combustion control at startingNo 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.
  1. Turn ignition switch OFF and wait at least 10 seconds.
  2. Turn ignition switch ON.
  3. 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.)
  1. Start the engine and warm it up until engine coolant temperature reaches 70°C (158°F) or more.
  2. 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
  1. Turn ignition switch ON (engine stopped).
  2. Select “COOLANT TEMP/S” and “INT/A TEMP SE” in “DATA MONITOR” mode of “ENGINE” using M.U.T.-III SE.
  3. Check that the indicated value of “COOLANT TEMP/S” is less than 35°C (95°F).
  4. Check that the difference between “INT/A TEMP SE” and “COOLANT TEMP/S” is 5°C (41°F) or less.
  5. Check “Self-diagnostic result” of “ENGINE”.
Is the DTC detected?
Proceed to DTC Diagnosis Procedure.
 
6.PERFORM DTC CONFIRMATION PROCEDURE-2
  1. Start the engine (or cranking) at least 1 second.
  2. Check “Self-diagnostic result” of “ENGINE”.
Is the DTC detected?
Proceed to DTC Diagnosis Procedure.
