DTC P1111, P1136 IVT CONTROL SOLENOID VALVE

Specification data are reference values and are measured between each terminal and ground.
Pluse 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

EBS00MH9

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 2 and ground with CONSULT-II or tester.

OK or NG

OK

>> GO TO 3.

NG

>> GO TO 2.
