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.

DIAGNOSTIC TROUBLE CODE CONFIRMATION PROCEDURE

CAUTION: Always drive at safe speed.

NOTE: If "DIAGNOSTIC TROUBLE CODE CONFIRMATION PROCEDURE" has been previously conducted, always turn ignition switch "OFF" and wait at least 5 seconds before conducting the next test.

With Consult
1. Warm up engine to normal operating temperature [more than 82 °C (180 °F)].
2. Turn ignition switch "OFF" and wait at least 5 seconds.
3. Turn ignition switch "ON" and select "DATA MONITOR" mode with CONSULT-II.
4. Restart engine and wait at least 30 seconds.
5. Turn TCS switch "OFF".
6. Shift A/T selector lever to "2nd" position.
7. Gradually raise engine speed and keep it between 1,100 rpm and 1,500 rpm for at least 20 seconds. (Test is completed when "INT/V SOL - B1 in "DATA MONITOR" with CONSULT-II remains "OFF". If indication is "ON", repeat 7.
8. Quickly raise engine speed to more than 2,500 rpm and keep it there for at least 6 seconds. (Test is completed when "INT/V SOL - B1 in "DATA MONITOR" with CONSULT-II remains "ON". If indication is "OFF", repeat 8.
9. If 1st trip DTC is detected, go to "DIAGNOSTIC PROCEDURE".

OR

With Generic Scan Tool
1. Warm up engine to normal operating temperature.
2. Turn ignition switch "OFF" and wait at least 5 seconds.
3. Restart engine and wait at least 30 seconds.
4. Turn TCS switch "OFF".
5. Shift A/T selector lever to "2nd" positions.
6. Gradually raise engine speed and keep it between 1,000 rpm and 1,500 rpm for at least 12 seconds.
7. Quickly raise engine speed to more than 2,500 rpm and keep it there for at least 6 seconds.
8. Select "MODE 7" with GST.
9. If 1st trip DTC is detected, go to "DIAGNOSTIC PROCEDURE".

OR

Without Scan Tools
1. Warm up engine to normal operating temperature.
2. Turn ignition switch "OFF" and wait at least 5 seconds.
3. Restart engine and wait at least 30 seconds.
4. Turn TCS switch "OFF".
5. Shift A/T selector lever to "D" position.
6. Gradually raise engine speed and keep it between 1,000 rpm and 1,500 rpm for at least 12 seconds.
7. Quickly raise engine speed to more than 2,500 rpm and keep it there for at least 6 seconds.
8. Turn ignition switch "OFF", wait at least 5 seconds and then turn "ON".
9. Perform "Diagnostic Test Mode II (Self-diagnostic results)" with ECM.
10. If 1st trip DTC is detected, go to "DIAGNOSTIC PROCEDURE".

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.
