DTC P1111, P1136 IVT CONTROL SOLENOID VALVE

Diagnostic ProcedureBBS0051U
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-II or tester.
OK or NG
OK >> GO TO 3.
NG >> GO TO 2.
2. DETECT MALFUNCTIONING PART
Check the following.

Harness connectors E11, E253

Harness connectors E102, M57

Harness connectors M52, F103

Harness connectors F1, F251 (bank 1)

Harness for open or short between intake valve timing control solenoid valve and IPDM E/R

Harness for open or short between intake valve timing control solenoid valve and ECM
>> Repair open circuit or short to ground or short to power in harness or connectors.
3. CHECK INTAKE VALVE TIMING 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 11 (bank1) or 10 (bank2) and intake valve timing control
solenoid valve terminal 1. Refer to Wiring Diagram.
4. Also check harness for short to ground and short to power.
OK or NG
OK >> GO TO 5.
NG >> GO TO 4.Voltage: Battery voltage

Component InspectionBBS0051V
INTAKE VALVE TIMING CONTROL SOLENOID VALVE
1. Disconnect intake valve timing control solenoid valve harness connector.
2. Check resistance between intake valve timing control solenoid
valve as follows.
If NG, replace intake valve timing control solenoid valve.
If OK, go to next step.
3. Remove intake valve timing control solenoid valve.
4. Provide 12V DC between intake valve timing control solenoid
valve terminals and then interrupt it. Make sure that the plunger
moves as shown in the figure.
CAUTION:
Do not apply 12V DC continuously for 5 seconds or more.
Doing so may result in damage to the coil in intake valve
timing control solenoid valve.
If NG, replace intake valve timing control solenoid valve.
NOTE:
Always replace O-ring when intake valve timing control
solenoid valve is removed.
