DTC Description

DTC DETECTION LOGIC

DTC

CONSULT screen terms

(Trouble diagnosis content) 		DTC detection condition
P0088 00

HIGH FUEL PRES

(Fuel rail/system pressure - too high) 		Diagnosis condition Engine running at idle
Signal (terminal) Fuel rail pressure signal
Threshold ECM detects that the difference between target fuel pressure and fuel rail pressure sensor signal is 2,700 kPa (27.54 kg/cm2, 319.5 psi)
Diagnosis delay time 5 seconds

POSSIBLE CAUSE

  • Harness or connectors (The high pressure fuel pump circuit is open or shorted.)

  • High pressure fuel pump

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.
Device fix mode

  • This mode fixes the electric IVT control actuator and the EVT control solenoid valve in the reference position.

  • A control signals is not transmitted to the EGR volume control valve and the EGR volume control is deactivated.
Combustion control mode Stratified charge combustion control at starting No stratified charge combustion at starting (cold start).

Stop/Start System

When a DTC is detected, the stop/start indicator lamp blinks slowly and the stop/start system operation is prohibited.

When ECM detects error while operating the stop/start system, ECM restarts the engine.

DTC Confirmation Procedure

CHECK DTC PRIORITY

If DTC P0088 is displayed with DTC P0090, first perform the trouble diagnosis for DTC P0090.

Is applicable DTC detected?

YES>>

Perform diagnosis of applicable. Refer to DTC Description.

NO>>

GO TO 2.

PRECONDITIONING

If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at least 10 seconds before conducting the next test.

TESTING CONDITION:

  • Before performing the following procedure, confirm that battery voltage is 11 V or more at idle.

  • Before performing the following procedure, check that the fuel tank is 1/8 full of fuel.

GO TO 3.

DTC CONFIRMATION PROCEDURE-1

  1. Check that the fuel tank is 1/8 full of fuel.

  2. Warm up the engine to the normal operating temperature and keep the engine speed at idle for 15 seconds.

    NOTE:

    Warm up the engine until “COOLANT TEMP/S” on “DATA MONITOR” of CONSULT reaches at least 70°C (158°F).

  3. Check 1st trip DTC.

Is 1st trip DTC detected?

YES>>

Proceed to DTC Diagnosis Procedure.

NO>>

GO TO 4.

DTC CONFIRMATION PROCEDURE-2

  1. Cool the engine until the engine coolant temperature reaches 60°C (140°F) or less.

  2. Start the engine and let it idle at least 40 seconds.

  3. Check 1st trip DTC.

Is 1st trip DTC detected?

YES>>

Proceed to DTC Diagnosis Procedure.

NO-1>>

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

NO-2>>

Confirmation after repair: INSPECTION END

DTC Diagnosis Procedure

CHECK DTC PRIORITY

If DTC P0087 is displayed with DTC P0090, first perform the confirmation procedure for DTC P0090.

Is applicable DTC detected?

YES>>

Perform diagnosis of applicable. DTC Description

NO>>

GO TO 2.

CHECK LOW FUEL PRESSURE

Check low fuel pressure. Refer to Work Procedure.

Is inspection result normal?

YES>>

GO TO 3.

NO>>

Check low fuel pressure system. Refer to Diagnosis Procedure.

CHECK HIGH PRESSURE FUEL PUMP

Check high pressure fuel pump. Refer to Component Inspection.

Is inspection result normal?

YES>>

GO TO 4.

NO>>

Replace error-detected parts.

CHECK FUEL LEAKAGE

  1. Start the engine.

  2. Visually check that the fuel pump, fuel rail, and fuel piping have no fuel leakage.

Is inspection result normal?

YES>>

Check that the fuel system has no breakage, bend, and crush. Refer to Inspection.

NO>>

Repair or replace the error-detected parts.
