IVT CONTROL SOLENOID VALVE
Specification data are reference values and are measured between each terminal and ground.
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
EBS00R3F
1.
CHECK IVT CONTROL SOLENOID VALVE OVERALL FUNCTION CHECK
1.
Start engine and warm it up to normal operating temperature.
2.
Turn ignition switch “OFF” and wait at least 10 seconds.
3.
Turn ignition switch “ON”.
4.
Set the tester probe between ECM terminals 62 (IVT control solenoid valve signal) and ground.
5.
Start engine and let it idle.
6.
Check the voltage under the following conditions.
Verify that the oscilloscope screen shows the signal wave as
shown below.
: Average voltage for pulse signal (Actual pulse signal can be confirmed by oscilloscope.)

2.
CHECK IVT CONTROL SOLENOID VALVE POWER SUPPLY CIRCIUT
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 4.
NG
>> GO TO 3.
3.
DETECT MALFUNCTION PART
Check the following.
●
Harness connectors M71, F45
●
Harness for open or short between intake valve timing control solenoid valve and ECM relay
>> Repair open circuit or short to ground or short to power in harness or connectors.
4.
CHECK IVT CONTROL SOLENOID VALVE OUTPUT SIGNAL CIRCUIT FOR OPEN AND SHORT
1.
Turn ignition switch “OFF”.
2.
Disconnect ECM harness connector.
3.
Check harness continuity between ECM terminal 62 and intake valve timing control solenoid valve termi-
nal 2. Refer to Wiring Diagram.
4.
Also check harness for short to ground and short to power.
OK or NG
OK
>> GO TO 5.
NG
>> Repair open circuit or short to ground or short to power in harness or connectors.
5.
CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE
Refer to
EC-902, "Component Inspection"
.
OK or NG
OK
>> GO TO 6.
NG
>> Replace intake valve timing control solenoid valve.
