DTC P0075, P0081 IVT CONTROL SOLENOID VALVE
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.

Diagnosis Procedure
INFOID:0000000001325986
1.
CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE 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-III or tester.
OK or NG
OK
>> GO TO 3.
