Diagnosis condition
Signal (terminal)Electric intake valve timing control position sensor signal
ThresholdAn excessively low/high voltage from the sensor is sent to the electric IVT control module.
Diagnosis delay time1 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 operating condition in fail-safe mode
Fail safe modeVehicle behavior
Device fix mode
  • This mode fixes the electric IVT motor and the EVT control solenoid valve in the reference position.
  • The intake manifold runner control valve motor is turned OFF (intake manifold runner control valve opens).
  • A control signals is not transmitted to EGR volume control valve and the EGR volume control is deactivated.
