P0011 IVT CONTROL

System Description:

Description
This mechanism hydraulically controls cam phases continuously with the fixed operating angle of the intake valve.

The ECM receives signals such as crankshaft position, camshaft position, engine speed, and engine coolant temperature. Then, the ECM sends ON/OFF pulse duty signals to the camshaft timing control valve depending on driving status. This makes it possible to control the shut/open timing of the intake valve to increase engine torque in low/mid speed range and output in high-speed range.

FAIL-SAFE MODE
When malfunction A or B is detected the ECM enters fail-safe mode and the MIL lights up.

DTC Confirmation Procedure

CAUTION: Always drive at a safe speed.

NOTE:
- If both DTC P1111 (B1), P1136 (B2) or P1140 (B1), P1145 (B2) and P0011 (B1), P0021 (B2) are displayed, perform trouble diagnosis for "DTC P1111 (B1), P1136 (B2) or P1140 (B1), P1145 (B2)" first.
- If "DTC Confirmation Procedure" has been previously conducted, always turn ignition switch "OFF" and wait at least 10 seconds before conducting the next test.

PROCEDURE FOR MALFUNCTION A

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




2. Select "DATA MONITOR" mode with CONSULT-II.




3. Maintain the above conditions for at least 10 consecutive seconds.




4. Maintain the above conditions for at least 20 consecutive seconds.

With GST
Follow the procedure "With CONSULT-II" above.

PROCEDURE FOR MALFUNCTION B

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




2. Select "DATA MONITOR" mode with CONSULT-II.




3. Maintain the above conditions for at least 20 consecutive seconds.
4. If 1st trip DTC is detected, go to "P1140, P1145 INTAKE VALVE TIMING CONTROL POSITION SENSOR".

With GST
Follow the procedure "With CONSULT-II" above.
