P1111

COMPONENT DESCRIPTION
The valve timing control system is utilized to control intake valve opening and closing timing. Engine coolant temperature signals, engine speed and throttle position are used to determine intake valve timing.

The intake camshaft sprocket position is regulated by oil pressure controlled by the intake valve timing control.

When PCM sends ON signal to intake valve timing control solenoid valve, oil pressure is transmitted to camshaft sprocket. Then, intake side camshaft is advanced.

DTC Confirmation Procedure

NOTE: If "DTC Confirmation Procedure" has been previously conducted, always turn ignition switch "OFF" and wait at least 10 seconds before conducting the next test.

With CONSULT-II
1. Turn ignition switch "ON".




2. Select "DATA MONITOR" mode with CONSULT-II.
3. Wait at least 5 seconds.
4. If 1st trip DTC is detected, go to "Diagnostic Procedure" below.

Without CONSULT-II
Follow the procedure "With CONSULT-II" above.

DIAGNOSTIC PROCEDURE

COMPONENT INSPECTION

INTAKE VALVE TIMING CONTROL SOLENOID VALVE
1. Check oil passage visually for any metal debris.




2. Supply intake valve timing control solenoid valve terminals with battery voltage.
3. Make sure that inside plunger protrudes.
If NG, replace intake valve timing control solenoid valve.
