(Trouble diagnosis content) 		DTC detection condition
P34AC 00

A camshaft posi actuator posi sens B1

(A Camshaft Position Actuator Position Sensor A Circuit Bank 1) 		Diagnosis condition —
Signal (terminal) Electric intake valve timing control position sensor signal
Threshold An excessively low/high voltage from the sensor is sent to the electric IVT control module.
Diagnosis delay time 1 second or more

POSSIBLE CAUSE

  • Harness or connectors [Electric intake valve timing (IVT) control actuator circuit is open or shorted.]

  • Electric IVT control actuator

FAIL-SAFE

Engine Control System

Fail safe mode Nissan Ariya Vehicle behavior
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

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.

GO TO 2.

PERFORM DTC CONFIRMATION PROCEDURE

  1. Maintaining engine speed at idle for at least 1 seconds.

  2. Check 1st trip DTC.

Is 1st trip DTC detected?

YES>>

Refer 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 ELECTRIC INTAKE VALVE TIMING CONTROL POSITION SENSOR CIRCUIT

  1. Turn ignition switch OFF.

  2. Disconnect electric intake valve timing control position sensor harness connector.

  3. Disconnect intake valve timing control module harness connector.

  4. Check the continuity between the electric intake valve timing control position sensor harness connector and the electric intake valve timing control module harness connector.

    5 6

  5. Also check harness for short to power and short to ground.

Is the inspection result normal?

YES>>

GO TO 2.

NO>>

Repair or replace error-detected parts.

CHECK INTERMITTENT INCIDENT

Check intermittent incident. Refer to Intermittent Incident.

Is the inspection result normal?

YES>>

Replace the electric intake valve timing control actuator. Refer to Exploded View.

NO>>

Repair or replace error-detected parts.
