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.

DTC P1111 IVT CONTROL SOLENOID VALVE

D T C P 1111 I V T C O N T R O L S O L E N O I D VA LV EPFP:23796
Component DescriptionEBS010R5
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.

WITH CONSULT-II
1. Turn ignition switch ON.
2. Select “DATA MONITOR” mode with CONSULT-II.
3. Start engine and let it idle for 5 seconds.

DTC P1111 IVT CONTROL SOLENOID VALVE

Specification data are reference values and are measured between each terminal and ground.
Pulse signal is measured by CONSULT-II.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.
: Average voltage for pulse signal (Actual pulse signal can be confirmed by oscilloscope.)
Diagnostic ProcedureEBS010RA
1. CHECK POWER SUPPLY CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect intake valve timing control solenoid valve harness connector.
3. Turn ignition switch ON.
4. Check voltage between intake valve timing control solenoid
valve terminal 1 and ground with CONSULT-II or tester.
OK or NG
OK >> GO TO 3.
NG >> GO TO 2.
2. DETECT MALFUNCTION PART
Check harness for open or short between intake valve timing control solenoid valve and ECM relay.
>> Repair or replace harness or connectors.
