ENG SPEED [rpm]××

Indicates the engine speed computed from the
signals of the crankshaft position sensor
(POS) and camshaft position sensor (PHASE).

speed drops below the idle rpm.

If the signal is interrupted while
the engine is running, an abnor-
mal value may be indicated.

is displayed.
When the engine is stopped, a
certain value is indicated.

“Base fuel schedule” indicates the fuel injec-
tion pulse width programmed into ECM, prior
to any learned on board correction.

is clamped, the value just before
the clamping is displayed contin-
uously.

DTC P0011 IVT CONTROL

DTC P0011 IVT CONTROLPFP:23796
DescriptionEBS010MG
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.

On Board Diagnosis LogicEBS010MI
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 ProcedureEBS010MJ
CAUTION:
Always drive at a safe speed.
NOTE:

If DTC P0011 is displayed with DTC P1111, first perform trouble diagnosis for DTC P1111. See EC-
290, "DTC P1111 IVT CONTROL SOLENOID VALVE" .

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.
4. Let engine idle for 10 seconds.
5. If the 1st trip DTC is detected, go to EC-138, "
Diagnostic Procedure" .
If the 1st trip DTC is not detected, go to next step.
6. Maintain the following conditions for at least 20 consecutive seconds.
7. If 1st trip DTC is detected, go to EC-138, "
Diagnostic Procedure" .
WITH GST
Follow the procedure “WITH CONSULT-II” above.
