P34AF 00

A camshaft posi actuator posi sens B1

(A camshaft position actuator position sensor A circuit high Bank 1)
Diagnosis condition
Signal (terminal) Electric intake valve timing control position sensor signal
Threshold An excessively 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 (motor 1 hall sensor)

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.
