EC-288
[QR (WITH EURO-OBD)]
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 Procedure EBS010RA
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.
