DTC P0011 IVT CONTROL

DTC P0011 IVT CONTROLPFP:23796
DescriptionEBS010XU
SYSTEM DESCRIPTION
*: This signal is sent to the ECM through CAN communication line.
This mechanism hydraulically controls cam phases continuously with the fixed operating angle of the intake
valve.
The ECM receives signals such as crankshaft position, camshaft position, engine speed, and engine coolant
temperature. Then, the ECM sends ON/OFF pulse duty signals to the intake valve timing control solenoid
valve depending on driving status. This makes it possible to control the shut/open timing of the intake valve to
increase engine torque in low/mid speed range and output in high-speed range.
COMPONENT DISCRIPTION
Intake valve timing control solenoid valve is activated by ON/OFF
pulse duty (ratio) signals from the ECM.
The intake valve timing control solenoid valve changes the oil
amount and direction of flow through intake valve timing control unit
or stops oil flow.
The longer pulse width advances valve angle.
The shorter pulse width retards valve angle.
When ON and OFF pulse widths become equal, the solenoid valve
stops oil pressure flow to fix the intake valve angle at the control
position.

The MI will not light up for this diagnosis.
FAIL-SAFE MODE
ECM enters in fail-safe mode when the malfunction is detected.
DTC Confirmation ProcedureEBS010XX
CAUTION:
Always drive at a safe speed.
NOTE:
If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at
least 10 seconds before conducting the next test.
TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is between 10V and 16V at
idle.
WITH CONSULT-II
1. Turn ignition switch ON and select “DATA MONITOR” mode with
CONSULT-II.
2. Start engine and warm it up to the normal operating tempera-
ture.
3. Maintain the following conditions for at least 6 consecutive sec-
onds.
Hold the accelerator pedal as steady as possible.
