DTC Description

DTC DETECTION LOGIC

DTC		M.U.T.-III SE screen terms (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 operating condition in fail-safe mode
Fail safe mode		Vehicle 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.
Combustion control mode	Stratified charge combustion control at starting	No stratified charge combustion at starting (cold start).

DTC Confirmation Procedure

1.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.

2.PERFORM DTC CONFIRMATION PROCEDURE

Maintaining engine speed at idle for at least 1 seconds.
Check 1st trip DTC.

Is 1st trip DTC detected?
