DTC Description

DTC DETECTION LOGIC

DTC

CONSULT screen terms

(Trouble diagnosis content) 		DTC detection condition
P0192 00

FRP SEN/CIRC

(Fuel Rail Pressure Sensor Circuit Low Bank 1) 		Diagnosis condition Engine running at idle
Signal (terminal) Fuel rail pressure sensor signal
Threshold Signal voltage from the fuel rail pressure sensor remains at less than 0.14V
Diagnosis delay time 5 seconds or more

POSSIBLE CAUSE

  • Harness or connectors (Fuel rail pressure sensor circuit is open or shorted.)

  • Fuel rail pressure sensor

  • 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).

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 P0192 is displayed with other DTC, first perform the trouble diagnosis for other DTC.

Is other DTC detected?

YES>>

Perform diagnosis of applicable. Refer to DTC Index.

NO>>

GO TO 2.

PRECONDITIONING

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

TESTING CONDITION:

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

>>

GO TO 3.

PERFORM DTC CONFIRMATION PROCEDURE

  1. Start engine and let it idle for at least 1 minute.

  2. Check DTC or 1st trip DTC.

Is DTC or 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

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.

CHECK DTC PRIORITY

If DTC P0192 is displayed with other DTC, first perform the trouble diagnosis for other DTC.

Is other DTC detected?

YES>>

Perform diagnosis of applicable. Refer to DTC Index.

NO>>

GO TO 2.
