DTC Description

DTC DETECTION LOGIC

DTC	CONSULT screen terms (Trouble diagnosis content)	DTC detection condition
P0012	A camshaft position B1 ("A" camshaft position - timing over-retarded bank 1)	Diagnosis condition	Ignition switch: ON Engine speed: 1, 200 - 3, 175 rpm Engine coolant temperature: 60 - 120°C (140 - 248°F) Battery voltage: 11 - 16 V
		Signal (terminal)	-
		Threshold	During the retarded control of intake valve timing control, the angle difference between actual angle and target angle is 13 degrees or more.
		Diagnosis delay time	6 seconds

POSSIBLE CAUSE

Electric intake valve timing (IVT) control actuator (bank 1)
Harness and connectors (Electric IVT control actuator (bank 1) motor control circuit is open or shorted.)
Foreign matter caught at the electric IVT control actuator (bank 1)

FAIL-SAFE

Fail safe mode	Vehicle behavior
Device fix mode	Fixes electric intake valve timing control motor in the reference position. Fixes exhaust valve timing control solenoid valve in the reference position.
Others	ECM stops the electric valve timing control. (The camshaft returns to the position of most retard angle. NOTE: When VTC mechanism sticks, camshaft position does not change from position of stuck angle.)
