P0011
DTC P0011 IVT CONTROLDescription
SYSTEM DESCRIPTION
The intake valve timing control system is utilized to control intake valve opening and closing timing. Engine coolant temperature signals, engine speed, amount of intake air, vehicle 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 ECM 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
CAUTION: Always drive at safe speed.
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.
TESTING CONDITION: Do not apply electrical load (e.g., cooling fan, rear window defogger, etc.)
WITH CONSULT-II
1. Warm up engine to normal operating temperature.
2. Turn ignition switch "OFF" and wait at least 10 seconds.
3. Turn ignition switch "ON" and select "DATA MONITOR" mode with CONSULT-II.
4. Restart engine and wait at least 30 seconds.
5. Let engine idle at least 50 seconds. (Test is completed when "INT/V SOL - B1 in "DATA MONITOR" with CONSULT-II remains "OFF".) If indication is "ON", repeat step.
6. Maintain the following conditions for at least 30 seconds. (Test is completed when "INT/V SOL - B1 in "DATA MONITOR" with CONSULT-II remains "ON".) If indication is "OFF", repeat step.
7. If 1st trip DTC is detected, go to "Diagnostic Procedure" below.
WITH GST
1. Warm up engine to normal operating temperature.
2. Turn ignition switch "OFF" and wait at least 10 seconds.
3. Restart engine and wait at least 30 seconds.
4. Let engine idle at least 50 seconds.
5. Maintain the given conditions for at least 30 seconds.
6. Select "MODE 7" with GST.
7. If 1st trip DTC is detected, go to "Diagnostic Procedure" below.

Component Inspection
INTAKE VALVE TIMING CONTROL POSITION SENSOR
1. Disconnect intake valve timing control position sensor harness connector.
2. Loosen fixing bolt of the sensor.
3. Visually check the sensor for chipping.
4. Check resistance between terminals 2 and 3.
Resistance: 600 - 740 Ohm [at 20 °C (68 °F)]
If NG, replace intake valve timing control position sensor.
