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 Control System

Fail safe mode Nissan Ariya 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

CHECK DTC PRIORITY

If DTC P119C is displayed with DTC P0192 or P0193, first perform the trouble diagnosis for DTC P0192 or P0193.

Is applicable DTC detected?

YES>>

Perform diagnosis of applicable.

  • DTC: P0192 Refer to DTC Description.

  • DTC: P0193 Refer to DTC Description.

NO>>

GO TO 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.

  • Remaining fuel amount must be 15% or more.

>>

GO TO 3.

PERFORM DTC CONFIRMATION PROCEDURE

  1. Start the engine and warm it up until the engine coolant temperature reaches 70°C (158°F) or more.

  2. Drive the Nissan Ariya vehicle and accelerate 10 consecutive seconds or more with the engine speed 1,500 rpm or more.

  3. Check “Self-diagnostic result” of “ENGINE”.

Is the DTC detected?

YES>>

Proceed to Diagnosis Procedure.

NO-1>>

To check malfunction symptom before repair: Refer to Intermittent Incident.

NO-2>>

Confirmation after repair: INSPECTION END

Diagnosis Procedure

NOTE:

Turning the ignition switch ON with FRP sensor harness connector disconnected causes ECM to detect DTC P0192 or P0193. Be sure to erase the DTC when the diagnosis procedure.
